<bone-baboon>I am getting this error "guix system: error: failed to load '/path/to/config.scm': No such file or directory" when I try to reconfigure a Guix system using a specific system configuration file. This is odd because ls shows the file and bash completion recognizes the file. I can reconfigure the system fine with another configuration file in the same directory. <bone-baboon>I can also look at the contents of configuration file in question with less. <civodul>bone-baboon: could it be that this config file includes another one? <civodul>or uses 'local-file' to refer to another file? <bone-baboon>civodul: It does not include another configuration file. Although this would be nice to learn about. What documentation should I look at to learn more about that? <bone-baboon>civodul: I just searched the configuration file for "local-file" and there was no match. <civodul>bone-baboon: weird; could you try "strace -o log guix system build /path/to/config.scm"? <civodul>then you look at the 'log' file, and searching from the end, see which file has ENOENT before the error message *bone-baboon building strace <zzappie>I just realized that services order in os record can take have effect on system.

If so I will install the substitute for strace. <civodul>bone-baboon: yes, but that's awkward: you have to "guix gc -D /gnu/store/*-strace*" and then "guix build strace" <lfam>You would also need to invalidate the garbage collector roots that refer the store item.

<leoprikler>sneek, later tell vagrantc that's much more a guile question in principle yes, but you'd need to hack extra machinery into resolve-module (more or less) <merazi>Hello, GUIX noob here. I hope you're all having a nice day/night. I have a question regarding package management, I've been using the Guix System just by calling the guix package command each time I want to install or remove software, and that works like a charm but, is there a way for me to remove some apps I'm not actually using? For example: I installed the GNOME desktop, which included Epiphany as a web browser (I installed icecat) and gedit as the text <merazi>editor (I'm using Emacs for that), I tried doing 'guix remove gedit' with no luck, sudo was not any better... So I'm a bit stuck here, Any suggestions? <merazi>sneek thank you! That's exactly how the epiphany icon looks for me. So... It is fixed on an update... I'll check tomorrow if there are any updates available, thanks again 😁 <merazi>Wait... That was merged one year ago, I should have the newest packaged version of epiphany <rekado_>merazi: does “guix describe” tell you that you’re using a recent Guix? <rekado_>merazi: regarding the removal of packages: the Gnome desktop service in Guix System includes packages by default. You cannot remove them when you use that service unmodified. <rekado_>to not have them installed you need to override the “gnome” package in gnome-desktop-configuration, the argument to gnome-desktop-service-type. <rekado_>the default “gnome” package includes the whole suite of Gnome packages, including epiphany. <sakalli>hi just to check i've understood this right. when i do 'guix pull' the repo gets updated, but the packages and system updates when i run, in my case, 'guix package -m manifestfile'. or is there another more idiomatic workflow? <rekado_>“guix pull” updates your Guix, which includes the full description of the world of software that Guix can access. <rekado_>all invocations of the “guix” command operate within that world defined by your current variant of Guix. <sneek>Welcome back pineapples, you have 1 message! <sneek>pineapples, raghavgururajan says: #48083 and #48091 <pineapples>sneek, later ask raghavgururajan: I'll wait, if I have to :) Thank you for your hard work! ***iyzsong-- is now known as iyzsong-w

<leoprikler>First, check whether it's really absolutely needed in both, and if you do add it with an explanation as to why. <Noclip>The manual says native-inputs is only for inputs needed only at build time but not at run time. Can I do it that way? <leoprikler>native means the code that should be compiled for the machine doing the building <mothacehe>civodul: now the only known installer issue left is the #f uuid, right? <leoprikler>or when some package only snarfs some constants from a shared library <GNUtoo>Hi, when building a system (vm, docker, etc) is it possible to copy a file to /etc/ ? <GNUtoo>Thanks, I'll try to grep for that <GNUtoo>Can the file come from a given package? <Frosku>Is there any way to make guix system reconfigure not run out of memory when compiling? I swear it's not supposed to take more than 32GB RAM to compile qtwebengine... <brendyyn>Frosku: assigning less threads to it may help <Frosku>What's the option for that? --cores=1? <brendyyn>how many virtual cores does your cpu have? <brendyyn>maybe set it to 12 or 8 and see what happens? 1 would likely take forever <GNUtoo>Does it really take that much memory while compiling? or does that happen during linking? <Frosku>GNUtoo: I dont know, it gets to 68% and then OOMs <Frosku>And takes absolutely forever so it's a pain to reproduce <GNUtoo>Many years ago, webkit and chromium already took quite a huge amount of memory at linking time with something like 8 cores <GNUtoo>They probably use things like LTO which are "Link Time Obtimization" <GNUtoo>AFAIK it puts everything in memory and try to do obtimizations <GNUtoo>but with many cores the amount of required RAM also increases a lot... <GNUtoo>And linking is usually done at the end... <Frosku>I'm just surprised it decided to die there instead of on i.e. the kernel <Frosku>Speaking of things that take painful amounts of time to compile, any chance of getting librewolf in the repo? <GNUtoo>what is librewolf? is it a game or a TLS library? <Frosku>It's Firefox without Mozilla branding <brendyyn>does it actually remove all nonfree stuff? <Frosku>Yeah, but that's drawn from an old version. <GNUtoo>So it might be possible to package that <GNUtoo>This is the version in Parabola: libre/iceweasel 1:87.0-1.parabola1 <brendyyn>for example firefox has some DRM stuff that icecat removes i think. <GNUtoo>Whereas in Parabola, icecat is older: libre/icecat 78.9.0_pre-2 <brendyyn>it says that librewolf includes DRM but disables it by default, so we would not package that i think <GNUtoo>So it should be pretty safe to package Parabola's iceweasel <Frosku>I think 88 so iceweasel would be good <GNUtoo>At the end of the day the same work probably need to be done anyway <GNUtoo>So to do that one needs to refresh the patch, not everything might be relevant for Guix though <GNUtoo>(to get the version 88 instead of 87) <civodul>mothacehe: yes, i think the main remaining installer issue is the (uuid->string #f) bug <civodul>there are older issues in the bug tracker, but i'm not sure if they're still relevant <pineapples>GNUtoo, brendyyn, Frosku: My two cents: I know this is not a make-a-wish message thread, but I'd love if we had Tor Browser packaged <brendyyn>pineapples: tor was submitted but didnt get in. now the patches are likely stale <pineapples>I've seen the patches, and I'm a little dejected by this fact <brendyyn>pineapples: ive seen a channel that supports running binaries from other standard distros. it may be more feasible to add that and run the upstream tor binaries. <brendyyn>pineapples: You can help by trying to resolve existing bugs to reduce load on reviewers <Frosku>qtwebengine failed on 8 cores, have set to 1... <brendyyn>did it look like it was only using 8 cores? <Noclip>It seems to be always recommended to download the tor browser bundle from the tor project website instead of compiling it locally or installing it through a repository. Even Nix seems to do that: " `tor-browser-bundle-bin` package is the official version built by torproject.org patched with `patchelf` to work under nix and with bundled scripts adapted to the read-only nature of the `/nix/store`." What's the reason for this? <brendyyn>Tor Browser has a design goal to remain indistinguishable from other copies of its self for anonymity. if we built it ourselves we could mess that up potentially <brendyyn>but also Nix devs dont care as much about building everything from source as Guix devs do <Noclip><brendyyn "Tor Browser has a design goal to"> Ok, that makes sense. <Noclip><brendyyn "but also Nix devs dont care as m"> Why not split up the guix package repo into two parts?: "main" stays the way the repo currently is and "alpha" allows not-so-clean package definitions to be added. That way guix could provide it's users with optional packages that are not yet bootstrapable. <merazi>rekado_ thank you for explaining, I just saw the messages <brendyyn>Noclip: We can create a channel for such things. <brendyyn>Noclip: I have been thinking of creating it, called "outerguix". It would be different from nonguix in that it would only contain free software, but just software that isn't packaged up to guix standards yet <Noclip>brendyyn: Yep, that's pretty much what I thought about. <Noclip>brendyyn: To get more than just 5 packages on such a channel it might help to officially support it and add it to the official guix bulid farm. <brendyyn>How can a probe in guile the arguments value of tests? for a package.

<Frosku>This qtwebengine build is using 22GB RAM on 1 core. <brendyyn>is your package modified from the default? <Frosku>Yes, in a way I cant discuss here :P <Frosku>Well, I can say there's a graft to replace mesa with something else <brendyyn>i wonder if you can lower the optimisation level to make it build faster for testing <Frosku>But that should only affect linking? <Noclip><Frosku "This qtwebengine build is using "> I'm not experienced with building packages from source but this sounds pretty crazy xD <Noclip>Frosku: Did you try building the original package?

My distro immediately carries my software :) <bone-baboon>I installed Guix on a computer using the 1.2.0 installer. I have since pulled and reconfigured many times. uname shows the kerenel version is still the version of the 1.2.0 installer. Do I need state the desired kernel verison in the system configurtion? <tissevert>yeah that's exactly how I feel : creating one's own packages has never been simpler and they are «real» packages with the same status as any other installed package, that feels like the «right» way to do it <Noclip>Is guix just a package manager or a distro generator ... (This is not a serious question.) <tissevert>maybe a good package manager should just be a distro generator ?… <bone-baboon>brendyyn: Good question I am not sure. I will try rebooting the computer. <brendyyn>bone-baboon: uname -a will show you the linux that is booted. you wont see the new one until you reboot <tissevert>c. 2010 I was playing a lot with squashed file systems, trying to get a script to generate a ro image to boot on, and never to modify it directly but instead regenerate a new clean image at every change <andreas-e>bone-baboon: And "uptime" will show you for how long your computer has been running. <tissevert>I was using an existing package manager to install the software into the target system before squashing, now guix feels like the best implementation I could dream of <tissevert>it gives me pure system I don't need to mess with but on the other hand I don't need expensive resquashing of all my root fs image each time I add a small utility <tissevert>yeah, I'd say a marvelous library for creating distros like you say brendyyn <Noclip><tissevert "c. 2010 I was playing a lot with"> When I got into linux I thought about something like that but had no idea how to do it. Now where I know Guix, Nix and Btrfs that probably won't be needed anymore. <civodul>tissevert: mothacehe gave a great talk at FOSDEM about using Guix to cross-build images for "embedded" systems <tissevert>yeah, I'm grateful I gave up long enough ago because that would've made my work completely obsolete ^^ (I still have a big crush for squashfs and unionfs though) <tissevert>I've been wanting to see if I could leverage guix to create light enough images for my small eeePC to use as a pokedex : ) <brendyyn>I ran (specification->package "foo") in a repl then suddenly guile dissapears saying its been nice interacting with you <tissevert>on our server but I didn't make the choice and I don't know much about it, I've mainly faced the consequences when it filled up and I had to flash-learn about rebalancing <tissevert>(longest downtime ever… t'was a sad day that day) *civodul amazed that bigloo was updated <Noclip>tissevert: But you do know about it's snapshot capabilities? <tissevert>Noclip: kind of. I know it's what it's good at, I know we have a systemd service that snapshots our / periodically (daily ?) but I haven't seen or used that part myself <tissevert>and I don't see clearly how it could interact positively with NixOS or GuixSD since profile generations already offer something similar <tissevert>or maybe reserved for data storage ? how do you use it ? are there cool tricks I haven't thought of ? <bone-baboon>brendyyn: Thank you. Rebooting worked uname now shows 5.11.16-gnu. <Noclip>tissevert: It should be somewhat similar to what you did with squashfs back then but much more powerfull, simpler and efficient. <Noclip>Yea, for the OS itself Nix/Guix should make btrfs snapshots obsolete. But you could still use it to take care of your data. <rekado>FWIW, ZFS snapshots have saved my butt a couple of times. <tissevert>but you mean there's a RO component with btrfs ? what I mainly like about squashfs is : it's so small I can fit it in RAM <rekado>when I accidentally let Guix delete part of /gnu/store due to misconfiguration <bone-baboon>Does that mean that whenever I build a new Linux-libre kernel that to start using it I need to reboot the computer? <tissevert>I hear about it every now and then, and each time I try to learn about it and wonder if I could be using it this time for this new disc I got it's always «no it's too complicated for you / you don't need it / not the right usecase» : ( <Noclip>Btrfs and ZFS are like siblings. <tissevert>rekado: how do you use it ? what's needed ? (last time I read about it I was confused about the «no formating» it seems to simply «stand there» on its own) <Noclip>tissevert: Yes both btrfs and zfs support RO snapshots. <tissevert>so I could use it for like «instant snapshot» instead of having to compress a dir into a squashfs ? <Noclip>As soon as a RO snapshot is created it is read only and can't be changed anymore. <rekado>tissevert: I don’t maintain the ZFS installation. <rekado>I merely wanted to mention that file system snapshots can be useful even in the presence of all the neat features Guix has to offer. <Noclip>Yes, snapshots are instantly / atomic on btrfs and zfs. <tissevert>rekado: ok ! thanks for that I'm not yet fully aware of everything guix offers and how it could still be augmented <tissevert>I haven't played enough with it to trash it badly : ) <rekado>tissevert: here at the institute ZFS is set up to snapshot directories once per day; I can access the past state via a hidden directory. <Noclip>rekado: Using snapshots on top of guix/nix should give you an additional level of security. <rekado>yeah, “convenience” is the word I’d use. <tissevert>is it like a kind of LVM / raid thing ? do you know if there is a file system formatted over it ? <rekado>sure, you *could* restore from backup, or you *could* reinstall based on the contents of manifests, etc, but just undoing a mistake by restoring a snapshot is usually quicker <rekado>but here it presents itself as just another NFS. <Noclip>Btrfs and zfs can replace most lvm features. <tissevert>oh, but maybe because it is actually served from a network server ? <brendyyn>how do i actually build a package from the repl? <tissevert>so is there like a «mkfs.zfs» ? I was looking for it last time I tried to give it a go and never found it and then a clowder of sys admins told me how it was mainly useful for virtualization clusters and it wasn't used like I generally use a file system (format / mount) <Noclip>tissevert: Also snapshoting is just one of the features btrfs/zfs support. There is also automated checksumming of every stored data and metadata block to prevent silent data corruption, data deduplication on the block level, multi-device support (somewhat like lvm), raid0 raid1 raid5 raid6 raid10 and built in data compression. <Noclip>I probably forgot some features xD <Noclip>tissevert: btrfs has mkfs.btrfs but I'm not sure about zfs. <brendyyn>copy on write is nice but it seems you need to use a special tool for it. if i just copy a file in gui file manager it copies very slowly <Noclip>I think ZFS doesn't make things always the way you would expect doing it on a linux system. Maybe that is because it's not really a linux filesystem in the first place. Btrfs is made specially for linux and does things as you would expect on linux. <Noclip>brendyyn: Which filesystem did you use for that? <brendyyn>i have a raid1 on luks encryption setup. i found that copying files was slow <Noclip>Was it significantly slower than on ext4? <Noclip>Btrfs should be a bit slower than ext4 but you should hardly notice that without benchmarking. <bone-baboon>I am trying to set up a substitute server. The substitute server is up after running guix publish. When I try to pull from the substitute server I get an authentication error.

How can I create an overridable operating-system declaration? e.g. I have a base config, then config A which adds a few packages, and config B which extends config A and adds some services and mount points <rekado>Guest3: “inherit” is the easiest way to accomplish this. <rekado>Guest3: in the “maintenance” repository, which defines the operating systems in use for the Guix build farm we use procedures to generate customized operating-system values. <rekado>this childhurd-os definition inherits unspecified fields from %hurd-vm-operating-system, and then overrides specified fields. <roptat>I was inspired by the maintenance repo, so it's definitely a good source too :) <Guest3>Thanks guys! That's exactly what I was looking for <Guest3>Also, what is required for a proper Guix boot? Can I delete everything other than /gnu and /boot? <leoprikler>Guest3: I don't think so. I'd leave at least /var untouched and without /home you're going to be quite unlucky (though your home can be reduced to just the skeleton) <wonko7>so how do I go about storing configuration files for wireguard? where do I put them? I've got a handful of files created by a vpn provider to switch between vpn endpoints, they usually live in /etc/wireguard <terpri>wonko7, i'd expect them to just go in /etc/wireguard as usual <terpri>speaking of which, /etc is another directory you'd need for to keep, Guest3 <wonko7>terpri: oh, right, I might have been overthinking things <Guest3>leoprikler: I'm trying to make my system completely immutable(other than modifications by guix system reconfigure).

I have another patch I want to send but it will have to be modified for the upcoming build system changes <leoprikler>I submitted v2 on the 17th, so the 14 day limit would be May 1st, which is the day after tomorrow. <leoprikler>I might make it May 2nd, since May 1st is Labour Day. <morgansmith>My patch is to make the emacs-org package reproducible. But I'm actually not entirely certain how to check reproducibility... guix --rounds doesn't do anything if the output is already built. then guix --check --rounds seems to verify against the installed output but I don't want that... <leoprikler>Hmm, if you're willing to rebase your patch onto 47661-v2, you could send it out now, let it be blocked by 47661 and potentially get some review done early, so that we can merge it quickly then. <morgansmith>It's a small patch. And it doesn't even really affect the user at all. I'm not super worried about getting it in soon. <morgansmith>In fact I'm worried it's not needed at all. How the heck can I confirm that emacs-org isn't building reproducibly? <leoprikler>garbage collecting emacs-org and rebuilding with rounds another <morgansmith>oh I did it! I got rid of the substitutes using 'guix gc -D /gnu/blah...' then I did 'guix build --no-substitutes --rounds=5 emacs-org'. Now I know that it isn't reproducible! <morgansmith>is this written out nicely in the manual and/or cookbook? I feel like it's important... <leoprikler>yep, now just send the output of diffoscope (or at least some subset) to bug-guix <leoprikler>It is somewhat documented as part of 16.6 Submitting Patches <morgansmith>oh. I just kinda skipped the analysis step and figured it was likely the autoloads. So I made a patch that throws away the org loaddef stuff and replaced it with out autoload stuff. Now it seems to be reproducible. I was right this time but doing a proper analysis might've been the right thing to do <morgansmith>nah, the 16.6 documentation isn't good enough for this. It's what I was referencing trying to get this done. We need to mention --no-substitutes and I really think --rounds should have an implied --no-substitutes <leoprikler>I'm not too sure about that, --no-substitutes is harder than you think <leoprikler>but I agree, that --rounds should disable substitutes particularly for the packages that were demanded <leoprikler>(at least rounds after 1, getting 1 substitute is fine) <morgansmith>rounds currently only downloads it once. meaning with substitutes on it's basically a no-op <morgansmith>ok, not a no-op but like --rounds doesn't modify anything at all <morgansmith>It's an argument that has no effect on the output of the command <morgansmith>oh and if you have the output already built then --rounds also doesn't do anything. So currently the only way to use --rounds as intended is to not have the output built and to have substitutes disabled. I think I take back what I said about the documention. I think the fault lies with how difficult it is to use the --rounds argument <leoprikler>nah, it stopped at "basically a no-op" for me and I'm currently writing mail on the other end <morgansmith>I just said this: if you have the output already built then --rounds also doesn't do anything. So currently the only way to use --rounds as intended is to not have the output built and to have substitutes disabled. I think I take back what I said about the documention. I think the fault lies with how difficult it is to use the --rounds argument <leoprikler>Yep, the weirdness of --rounds is a known issue. <leoprikler>I think the way people handle it is "guix environment <package> && guix build <package> --no-substitutes --rounds" ***lukedashjr is now known as luke-jr

<morgansmith>so I'm very confused with the emacs build system. So we run the install phase before the build phase. Meaning the .el files get bytecompiled in the store. However, when a file being compiled queries `load-file-name' it returns a path in /tmp. But it can't find the other files it needs to find from that path so I'm pretty sure that files aren't actually in /tmp <leoprikler>hmm, could you paste that with a dummy package, that prints load-file-name at compilation time? <ilmu>how do I set environment variable in the system config? <morgansmith>oh wait. I'm wrong. All the things do make it into /tmp and apparently that's where we are loading the files from. but the autoloads file doesn't make it into /tmp even though it is built. But when do we put things in /tmp? I'm very confused <bone-baboon>I am trying to build an i686 package on a x86_64 computer. `guix build --no-substitutes --system=i686-linux go-gopkg-in-yaml-v2` starts building Python-3.8.2 which is not listed as a dependency in the output of `guix search go-gopkg-in-yaml-v2`. Am I doing something wrong? <roptat>bone-baboon, it could be a dependency of a dependency <roptat>actually, with --no-substitutes, it's probably one of the core packages, before the final toolchain even <roptat>--system will build using the given architecture, so it's the same set of derivations as if you were building on i686 directly (it's native i686 compilation because your CPU supports it) <roptat>so if you've never used --no-substitutes for i686 binaries before, it's expected that you don't get a substitute and start building stuff deep in the dependency graph <civodul>sneek: later tell samplet yay for Disarchive support! \o/ <Guest3>Is it possible to re-export an entire imported module? <daviid>Guest3: if you mean the public interface of a guile module, then yes <Guest3>roptat: yeah that looks like it, thanks <roptat>\o/ looks like I finally have a working frama-c package! <apteryx>civodul: I have noticed overdrive1 is unreachable from berlin (via ssh); do you observe the same? <apteryx>fortunately it is still reachable from my machine <apteryx>but it has a tendency to fail offloads with <eof>, perhaps due to high load <civodul>apteryx: let's take it off berlin, temporarily <civodul>apteryx: i've stopped cuirass-remote-worker there (a bit abruptly), so it's all yours now! <apteryx>thanks! I'll start a release run now <civodul>you can use it for aarch64 and armhf <apteryx>yes, that's how it's defined in my local machines.scm file :-) <apteryx>and powerpc64le goes to p9.tobias.gr <civodul>yeah it's building things, but it seems to be okay <apteryx>is it something common to get that <eof> reply when the machine is too loaded? <civodul>perhaps we could temporarily turn off the coordinator though, nckx? <civodul>apteryx: i don't think so, i've only seen it recently on berlin, so i'm not sure what's wrong <efraim>My understanding is that should be fine <apteryx>I'm not sure what it's caused exactly, that's just my suspicion <civodul>it could be that, we'll have to investigate <civodul>i had a vague recollection of doing that for Guix but i can't find it *zzappie just stepped into unknown teritory... infieriors... <civodul>uh, the comment above was meant for #guile <zzappie>I want to make guix package of guix checkout that is used in my %load-path to be available inside derivation <zzappie>create inferior -> lookup guix package -> pass guix package to with-extensions -- Is this the right approach? <civodul>zzappie: i'm not sure i follow, could you explain in more detail? <zzappie>civodul: haha, im basically trying to reuse (gnu services ...) code. This fails due to the fact that package patches are not copied to the build side. Maxime (don't know the nick here) suggested me to just include guix in with-extensions and use inferior to ensure that I have same guix package as one that im using <zzappie>but I get incopatible bytecode errors anyways <zzappie>I also thought of maybe I need to note which guile is used in guix inferior package and pass this inferior guile to #:guile-for-build... <zzappie>but at this poing it goes beyond level my understanding of guix innerworkings and I feel like im just doing weird stuff <civodul>adding guix to with-extensions sounds reasonable <civodul>it gives you access to all the guix modules <civodul>but then, i'm not sure where the inferior comes in <civodul>perhaps that was discussed on the list? <civodul>i should read before saying anything stupid :-) *civodul has failed to follow help-guix for weeks :-/ <zzappie>I thougt that point of inferior is to make sure that guix package corresponds to guix in load-path <civodul>zzappie: is your end goal to build a derivation inside a derivation? <civodul>that'd be nice but it's not possible currently <civodul>(the Nix folks have been working on it, "recursive Nix" is the keyword) <zzappie>the goal is actually to invoke services inside services :D <zzappie><it's not possible currently> this note pobably saved me a lot of time <civodul>but, there are other things you can do, like using eval/container <civodul>this one is explicitly for things with side effects, one of which is talking to the daemon <zzappie>civodul: hmm... But Im not sure that I will endup in a situation wher I'll need recursive Guix <zzappie>shepherd is not running derivations its all plain scheme files <ryanprior>What's the point of recursive nix / derivations inside derivations? <ryanprior>(web searching now to see what people already wrote about it) <zzappie>is this an exmple of mystical multistage code? <drakonis>it lets them do chunkier and complex things that would normally not be possible with nix <ryanprior>Okay, the sense I'm getting is that if we had this in Guix, we could use it to defer package definitions upstream <ryanprior>You could write a package definition that's basically like "go fetch from this git repo, look for a package.scm file, and build the derivation as per the definition there" <drakonis>i'd like to be able to defer package definition to be able to generate hashes <drakonis>hmm, the ability to do rapid experimentation with a package or a CI i suppose? <ryanprior>what's standing in the way of your rapid experimentation presently <ryanprior>for me it's lack of cacheing. if a package takes 5 minutes to build and I have a problem with the tests, then every test cycle is at least 5 minutes long, very boring <ryanprior>if I could say "re-use the cached build stage from last time" this would enable my rapid experimentation with packages <ryanprior>docker and earthly already do this automatically =D <rekado>civodul, apteryx If you’re having network problems with berlin, please do let me know. <civodul>rekado: i'm not sure we do! it might just as well be something else, but thanks :-) <rekado>IT implemented the firewall changes I requested, which includes deleting unused rules. <rekado>(“unused” as confirmed by mothacehe) <drakonis>but then i believe i could use a function to generate the hashes maybe? <cybersyn>i come across a lot of interesting ideas from nixos. does anyone here use it in addition to (not on top of) guix? i have a laptop could run it on, but its obviously simpler to organize as many devices as possible with only guix. <ryanprior>drakonis: I do not understand which hashes you would want to generate or update *shrug* <ryanprior>The less I have to think about hashes (as an end-user) the better imho <apteryx>rekado: I think we're good, some things in our /etc/guix/machines.scm don't work anymore; they should be updated to use overdrive via its wireguard interface <ryanprior>Hashes to me are like assembly code, as a professional I care about it, as an end user I never want to see it <ryanprior>drakonis: what prevents you from doing this now (and does it have something to do with hashes) <apteryx>roptat: weird, once in a blue moon I get some error about a node not found in the italian translation. Clearing the tree and trying again works fine. Do you sometimes have this kind of very rare failure? <apteryx>drakonis: if you want to setup your own CI you probably want to configure the cuirass service <ryanprior>I would like to have a guix-in-docker so I can easily use Guix in third party CI pipelines (like the corp git forges provide) <ryanprior>I don't have any experience with Cuirass, would love to learn <zzappie>ryanprior: you can use "guix system docker-image config.scm" to generate guix-in-docker <zzappie>yes it has to return operating-system record <ryanprior>Okay well eventually I will try that, has somebody else already done this and pushed it to dockerhub? <zzappie>there is actually even a template for that guix/gnu/system/examples/docker-image.tmpl <ryanprior>okay damn writing all this down, I thought it was more complicated for some reason <ryanprior>we should put out a canonical minimal Guix image on dockerhub though <zzappie>yes there are some guix continers on dockerhub. But hey its guix make your own ;) <ryanprior>less friction if people don't have to do this themselves <leoprikler>I think the problematic part about that is the bootstrapping process. <leoprikler>There are some alpine/guix recipes out there, so if you have that + config.scm, you can bootstrap your first real guix in docker in CI hopefully <bone-baboon>What part of the output of `glxheads` would tell me if a GPU has 3D capabilites? 3D capabilities is part of the h-node reporting for a video card. Looking at video cards listed on h-node it looks like those that have 3d capabilities show the output of `glxheads`. <zzappie>civodul: Taking guile from guix inferior and building gexp refering to guix inferior package works!
