<Apteryx>Is (compose list proc) equivalent to (list proc) ? <Apteryx>Where do the logs of our services typically go? Is there some general mechanism taking care of this (by say, shepherd) ? <Apteryx>And why do our dhcp-client-service requires "'(user-processes udev)" ? <Apteryx>It's so quiet! Is everyone reeling from FOSDEM? ;) ***Piece_Maker is now known as Acou_Bass

<Apteryx>Is there a way to guarantee the ordering in which the services start? <Apteryx>I'd like wpa-supplicant-service to always start before dhcp-client-service, for example. <Apteryx>Any way to debug "starting" a service? I just reworked one, and it fails with 'ERROR: Wrong type to apply: "/gnu/store/.../dhclient"' <Apteryx>I'd like to put exercise the code from the repl, if possible. I can instantiate the service, but not sure how to "start" it. <roelj>If someone installs GNU Guix using the "binary installation" instructions. Where can the GNU Guix source code be found? <roelj>Apteryx: guix package --list-available works, so the package definitions should be somewhere locally.. <CharlieBrown>roelj: The Guix site shows you how to generate the binary. <Apteryx>roelj: Probably "guix build guix" would point to the store location? <Digit>i've never actually read the guix code. i imagine it might be a treat to read. <roelj>Digit: I learned a lot from it! <Digit>ACTION wrestles rainbow delimiters back onto his emacs ***fkz__ is now known as Guest37382
<civodul>roelj: i think we lost track of each other after your talk, but i wanted to say i liked it <civodul>definitely an improvement over the existing pipelinish tooling <Digit>oh yes! talks n things are happening around this time... ~ i've been distracted with medical things. yay. now lets see... nope, not libreplanet... that's end of march.... what else is on? <roelj>It still has a long way to go to prove itself.. :) <civodul>roelj: right, but it's a worthwhile direction, i think people will realize that :-) <roelj>civodul: thanks :) it gives me the confidence I'm not doing something stupid :) <roelj>civodul: I'd love your opinion on the record-type field naming. <Digit>ACTION snaps fingers, says "fosdem!" and shoots off with purpose <civodul>roelj: during the presentation i thought that maybe you wouldn't need the <package>-style 'inputs' field since you can use gexps <civodul>but the record field names looked good i think :-) <roelj>civodul: right. First time I showed that I confused the person I was showing it to, because it seems hard to imagine that one symbol holds the actual contents of a package.. While a package recipe seemed all straightforward.. :) <roelj>civodul: I'll see if I can simplify that indeed. <thomasd>I can't find a manual section on how to delete a system profile generation. Do I just remove the link from /var/guix/gcroots/profiles, or is there a clean way? <civodul>thomasd: well, turns out there's still no command to do that :-) <civodul>but it boils down to "sudo rm /var/guix/profiles/system-N-link" <civodul>although you have to make sure to pick the right N <civodul>it's ridiculous we don't have 'guix system delete-generations' tho <thomasd>OK, I wanted to check. Yes, it's ridiculous ;-) <thomasd>Well, plenty of HD space left, I'll just wait a while longer. Probably someone will implement that before I run out :) <thomasd>also, there is a slight inconsistency between `guix package --list-generations` and `guix system list-generations`. But there's probably a reason for that? <civodul>thomasd: there's no good reason i think <civodul>there was a discussion on revamping 'guix package' in the past but nothing really came out of it <civodul>in that case it's also that there's was no consensus on what the right thing would be <bnw>guix-cloudflare.tomli.me and guix-amazon.tomli.me seemed to be faster when I tried, but they both would stop before even a single package finished transferring. <bnw>with error message "TLS error in procedure 'handshake': The TLS connection was non-properly terminated. ... substituter 'substitute' die unexpectedly." <bnw>I think it has something to do with the GFW of China. <rekado_>when I lived in China the connection to AWS would be consistently unreliable. <bnw>rekado_, Yeah. Kind of annoying. <thomasd>after deleting a system profile link, should I run guix system reconfigure to generate a new grub.cfg, or is there another way to remove the now invalid entry from grub? ***jonsger1 is now known as jonsger

<thomasd>to answer my own question, yes, it seems that's the way to go :) <thomasd>I'm afraid to run guix gc for the first time on this system, though :P <civodul>thomasd: don't be afraid, everthing's gonna be ok <roelj>The gc is very effective.. I once tried to gc with an invalid localstatedir and it actually removed the entire store :D. If you don't mess with the NIX_STATE_DIR variable, I believe it's entirely safe. <thomasd>I recall some bugs with undetected references (fontconfig) but I thought those were solved, yes <ryanwatkins>Hey guys, is there a bluetooth package in guixsd currently? <ryanwatkins>civodul: I just saw, but does it also provide utils for client side usage? <civodul>dunno, i'm quite ignorant about Bluetooth <ryanwatkins>hmm, I think (bluetooth-service) and bluez package w/ bluetoothcti should do the job :D <rekado_>ryanwatkins: the bluez package contains bluetoothctl <rekado_>I used that to connect to a bluetooth speaker <bnw>If I am able to find someone or organization that is willing to mirror guix. Is there a more convenient way to sync the repo? Like rsync vs https? <ryanwatkins>rekado_: the bluetooth service daemon requires a restart right? <bnw>rsync other than https <rekado_>ryanwatkins: I don't know if it needs restarting. I'm sure it needs to run :) <roelj>Can I use the binary installation and have the profiles in /gnu/profiles? <rekado_>bnw: I don't know of an easy way to mirror hydra. I wonder if we should start an rsync server on hydra to allow for syncing the disk contents. <bnw>I am going to file an issue at github.com/tuna/issues tomorrow and see if they are able to mirror a repo to mainland China. <civodul>but of course, that's only useful if there are enough users of that mirror <rekado_>civodul: what do you think about a low-level sync at the file system level? <civodul>rekado_: that sounds more complicated/risky no? <civodul>we'd expose all of /gnu/store over rsync? <rekado_>maybe providing access only through a read-only FUSE layer. <bnw>I can't install guix on a vm if connection keeps failing, which is quite often due to all kind of disturbance at backbone portal to the outside world. <civodul>rekado_: and you think that'd be more efficient? <rekado_>civodul: it's about being able to fetch everything regularly without needing to know the individual store items. <rekado_>the nginx mirror setup only acts on a cache miss. <civodul>maybe we should rather expose the compressed nars? <rekado_>I'm having a hard time building the latest libreboot release. <rekado_>the fact that it is so very unlike any other GNU package makes it hard for me. <rekado_>it has a custom "build" script that is supposed to do certain things <rekado_>but I can't even build the info documentation because the texi files aren't included. <rekado_>has anyone here built libreboot from source yet? <rekado_>I find the documentation *very* hard to follow. <rekado_>Since reinstalling GuixSD with full disk encryption I have to do this very time consuming dance on each reboot: <rekado_>enter console, type "crypt<TAB> -a", input passphrase, wait, ESC, edit last item to add (crypto0) to the search, F10, ESC, select boot from (crypto0), dismiss warnings/errors. <rekado_>so I'm looking for a way to update the contents of my SPI chip and have it include a better grub.cfg. <rekado_>here's another GuixSD question: I use full disk encryption and on booting Linux I'm told that there was a problem with my file system. <rekado_>I'm dropped into a bournish REPL, but there's nothing available <rekado_>how can I access fsck in that REPL when the root fs isn't available yet? <rekado_>there seems to be fsck (because that's what's running before I'm thrown into the recovery REPL), but I can't run it from the REPL. <thomasd>rekado_ : I had a similar problem while trying different kernel versions (I'm now happily on 4.9.8 and no longer have problems), when I quit the shell, GuixSD continued to boot as normal <thomasd>in my case, no disk encryption was involved though <rekado_>yes, I can exit the REPL and it continues booting. <rekado_>but I'd like to fix the file system errors at that point. <rekado_>I'll reboot soon and then check what the PATH is. <jonsger>rekado_: did you check out librecore? it's a fork of libreboot <dale>In order to use emacs' tramp mode from my laptop to a guix-sd system, I have found that I need to put symbolic links to the programs id, ls and sed into /bin. Have others come across this/is there another way? <rekado_>jonsger: thanks, I haven't heard of it before. I'll take a look. <rekado_>dale: this was reported before. I forgot the details; ISTR that there's a TRAMP variable you can set to find programs on the remote end. <dale>Ah, yes, that would work also. But seems wrong to inconvenience every user separately rather than dealing with the issue once and for all. <civodul>dale: yeah the details are in the help-guix archive for now <Apteryx>Hello Guix! Do the service definitions end up in the store? I can't find the one I'm trying to debug, even using strace... <Apteryx>I would have expected "herd start networking" to load some service script (gexp in guix sources) from the store <Apteryx>And, another question: Is there any way to verify that a service definition "works" at the Guile REPL? <Apteryx>Something equivalent to "herd start my-service" <civodul>Apteryx: to test your service definition, you can run "guix system vm foo.scm" and run "herd start my-service" in there <civodul>for your 1st question, you can try "guix gc -R $(guix system build foo.scm) | grep shepherd-" <Apteryx>civodul: Thank you for your answers :) <bavier`>civodul: are the scripts that generate the website in a git repo? <civodul>bavier`: yes, see the link at the bottom of web pages :-) <bavier`>civodul: hmm, ok. But who/what 'git clones' that repo and runs haunt? <bavier`>I was wanting to get the output of 'git describe' in the package source links on the packages page, but I need some way to pass that info into the scheme code <Apteryx>Why do "(append (quote ("a" "b") '("c")) <Apteryx>nevermind, this was meant for the repl :o <bavier`>I guess (www packages) could locate the guix source directory in GUILE_LOAD_PATH and run (open-pipe* "git" "describe"), no user intervention required <sankey>if i run `guix pull`, does that update the guix distribution for all users on the system? I assume not, because that would have a side-effect <sankey>i wonder how to update the guix package definitions for all users on the system without having to run it once per user <Apteryx>sankey: The only way I can think of would be to add the packages to be shared at the "system" level (directly to the system config.scm file). <Apteryx>And then running "guix system reconfigure /your/config.scm" <Apteryx>But even then, if a user installed another version of a package in config.scm, it won't be touched. <davexunit_>sankey: we don't have anything to do that. letting each user have full control over their guix environment is a feature. <Apteryx>err, "sudo guix pull && sudo guix system reconfigure /your/config.scm" <sankey>i admire that, ans i'm not suggesting that guix pull should have side effects <davexunit_>you could make, say, /usr/local/bin/guix a symlink to the root user's guix <civodul>bavier`: currently there's a dirty script that updates the package pages daily on hydra.gnu.org <sankey>i wonder if there can be a `guix pull --use-latest-already-downloaded` <sankey>network and CPU on my system are very limited <mvb>sankey: You could point all users' "~/.config/guix/latest" symlink to a shared location <civodul>bavier`: but the goal is to clean that up and move it to bayfront.scm <sankey>mvb: indeed i've thought of that hack <bavier`>civodul: does invoking "git describe" from the scheme code seem alright to you? <sankey>mvb: wouldn't that link get overwritten by the next guix pull? <davexunit_>yeah, it would. users would have to not run that. <sankey>i am the user, and I can remember to not run that :) <sankey>normal users don't have access to the root user's /root/.config/guix/latest so I can't simply make that symlink into my normal user's $HOME/.config/guix/latest <mvb>a git checkout is probably easiest <davexunit_>a symlink in /usr/local/bin to /root/.guix-profile/bin/guix will do <davexunit_>you'll need to install a guix package that is the version you want <mvb>root's guix executable will still work with $HOME/.config/guix/latest for the active user <davexunit_>there's simply no way around that ever, without forking guix to remove that <mvb>it could be useful to make `guix pull` add the symlink to an arbitrary location <sankey>i would like that, but also to make guix pull determine which guix-latest, among those already installed, is the newest ***snape`` is now known as snape
<sankey>but meanwhile i'll probably just use a git checkout <mvb>you could have a "guix" user whose home directory is world-readable and use that for "guix pull" <sankey>indeed, it just occured to me that guix pull does some heavy lifting that i'd rather not script around using a git checkout <sankey>so a shared "guix-pull" user could be easier <sankey>honestly I already have on my TODO list: "explore new features for guix pull" <rekado_>how can I watch HTML5 videos in icecat or epiphany? <rekado_>I’m supposed to review the recordings of two FOSDEM talks <rekado_>and the review system requires me to be able to watch the videos in the browser and push buttons <rekado_>(normally I’d just use mpv, but I can’t push buttons with mpv) <catonano>rekado_: in Fedora and Ubuntu you need to install gstreamer plugins in order to watch footages in the browsers <rekado_>catonano: thanks for the hint.

So I had to run “e2fsck /dev/mapper/root”, which seems to have fixed the corrupted file system. <emyles>janneke: Should I have used a seperate store for my experiments with a git checkout and ./pre-inst? <janneke>emyles: i'm not sure what the situation is that you're in now <rekado_>emyles: using the same store is fine as long as you configure with “--localstatedir=/var” <sneek>catonano, you have 1 message. <sneek>catonano, rekado_ says: In the REPL I only have one directory in my PATH: e2fsck. So I had to run “e2fsck /dev/mapper/root”, which seems to have fixed the corrupted file system. <rekado_>catonano: you may have to use a different device node, dependent on what you named it. It’s called “root” in my case. <rekado_>catonano: BTW with all the gstreamer plugins installed I see a properly sized box where the video should be and I can hear the sound. <rekado_>still don’t see any video, but I guess that’s just a matter of fiddling with the gstreamer plugins. <emyles>janneke: okay, thanks a lot for the help, I didn't specify a --localstatedir because I thought it would default to the existing /var/guix <jmi2k>What's your opinion on Guix being used to distribute non-software related packages? Like books, artwork, presentations... I think it would be a nice concept, aside from the official repo. <rekado_>jmi2k: it could be argued that we already do this to some extent. <rekado_>we have a package for SICP (*the* book on Scheme) in Info format. <jmi2k>rekado_: really? I didn't know! I've heard someone talking about something on that line here before, and I fell in love with the concept. Also, when Guix gets channels, it could be even better <janneke>emyles: ouch...good to know that now <rekado_>emyles: unfortunately, the default value for localstatedir is usually not what you want for Guix. It’s the default due to compliance with the GNU build system standards :-/ <jmi2k>I'm packaging Google Material Design icon font, what name is better: font-google-materialicons or font-google-material-design-icons?
