<gnucode>hey friends...

<gnucode>so I could use some help fsck-ing my / filesystem

<gnucode>nevermind fsck is in progress

<gnucode>That was the first time X locked up and me and would not respond within 5 minutes. I did a hard shutdown...

<gnucode>Ctrl-Alt-Del did not kill the X server unfortunately.

<youpi>did you configure it ?

<youpi>see https://www.debian.org/ports/hurd/hurd-install

<gnucode>youpi: I did configure ctrl-alt-del

<gnucode>it did work before. :)

<youpi>(note that it's backspace, not del)

<youpi>ok

<gnucode>yes. It's fsck-ing now. hopefully it still works. Will found out soon

<gnucode>find*

<gnucode>interestingly when / is not mounted "halt" and "poweroff" do not work. makes sense since binaries are located in /

<youpi>? "/ not mounted" ?

<youpi>we basically always have a /

<youpi>but halt/poweroff need a properly running init

<gnucode>might not be a bad idea in my next install to have a seperate /usr/bin partition

<youpi>to be able to tell it to shutdown/reboot

<gnucode>oh that would make sense

<youpi>so you want to use halt-hurd or poweroff-hurd

<gnucode>yup that worked! thanks

<gnucode>rebooting now, let's see how bad the damage is...

<gnucode>hahaha

<youpi>(that's just the same on linux with sysv init)

<gnucode>ok. I'm not complaining. just reporting. I definitely want to try to make this my daily work laptop and see how far that gets me

<gnucode>hmmm that's weird. showtrans / or showtrans /home does not show a translator running...

<youpi>showtrans only show passive translators

<youpi>not active translators

<gnucode>ok. Also X is giving my some trouble now. something about having difficulty in locking the .Xauthority file

<nikolar>wonder how hard it is to write a new filesystem/translator for hurd

<nikolar>i am working on a fs and might be open to porting it just for fun :)

<youpi>it depends what you call "hard"

<youpi>it's basically similar to adding a fs to Linux

<youpi>difference being that you can run it in gdb etc.

<nikolar>Well I have no clue what kind of api/interface I'd be dealing with

<youpi>basically the same kind: fill the lookup / read / write / etc. hooks

<nikolar>What's the simplest translator I can take a look at

<nikolar>Probably something like symlink

<youpi>fatfs perhaps?

<youpi>symlink is not a full fs

<nikolar>Oh yeah fair enough

<youpi>that won't show you lookup etc.

<nikolar>Yeah got it

<nikolar>I imagine there's little documentation other than the code itself

<youpi>there is the libdiskfs chapter in the hurd doc

<nikolar>Cool

<nikolar>Thanks

<nikolar>How long does it even take to build Hurd lol

<nikolar>I imagine nowhere near as long as linux

<youpi>well, you can just build your own translator and that's it

<youpi>that'll be less than a second

<gnucode>what kind of file system are you working on?

<nikolar>A log based filesystem for by bachelor's

<nikolar>Something like zfs/btrfs

<nikolar>But basically as simple as I can get it implementation-wise

<gnucode>kk awesome

<nikolar>It is pretty fun

<gnucode>hmmm so apparently my /home directory is mounted read-only

<youpi>perhaps you missed enabling auto-fsck in /etc/fstab ?

<gnucode>that is entirely possible. but normally fsck runs by default. except last time it was so bad that it made me manually fsck. I will check

<youpi>no, fsck doesn't run by default unless it's specified so in /etc/fstab

<gnucode>running fsck now on my /home directory

<gnucode>we should be in business

<gnucode>it works!

<gnucode>so now I am off to figure out how to auto-fsck /etc/fstab. no need to tell me how, I shall endeavor to discover how to myself

<youpi>hint: man fast

<youpi>man fstab

<gnucode>youpi: man fstab -> No manual entry to fstab

<gnucode>I will have to google it

<gnucode>ok I have to leave, thanks again for the help as always youpi!

<youpi>bleh, fstab.5 is in the mount package, which is linux-only

<gnucode>so I am pretty sure that my fstab does run fsck by default

<gnucode>the last field on the right for / is 1

<gnucode>2 for /home

<gnucode>so fsck check / first. then /home.

<gnucode>I think the hard drive was so corrupt that it just made me re-check...

<Gooberpatrol66>the link to "generalizing mobility for the hurd" on this page gives 403 forbidden https://www.gnu.org/software/hurd/hurd/documentation.html

<Gooberpatrol66>here's a working link https://web.archive.org/web/20160214235228/http://users.student.lth.se/cs07fh9/2009-hammar-hurd-mobility.pdf

<gnucode>hey friends, ya'll will be glad to know that the filesystem corruption that I had yesterday didn't seem to affect anything.

<gnucode>My T43 is still chugging along.

<nikolar>good to hear

<nikolar>hurd could really use a more resilient fs

<gnucode>nikolar: I do agree. :)

<gnucode>How hard/difficult is your filesystem class?

<nikolar>oh it's not a class

<nikolar>it's a dissertation

<nikolar>and i am intentionally making it as simple as i can

<gnucode>so you are going for a PHd?

<gnucode>You might get some inspiration from the ext3 translator. I don't think it so super stable, which is why it was never committed. But it was worked on.

<gnucode>honestly I don't really know much about filesystems, but they sure sound cool!

<nikolar>gnucode: not a phd, a bachelor's actually lol

<nikolar>nowhere close to a phd

<nikolar>honestly, i need to know how to interact with the rest of the system

<nikolar>not how the particular fs is implemented

<nikolar>so the simpler, the better

<gnucode>nikolar: maybe this is too far fetched, but bcachefs has a FUSE module

<gnucode>but maybe that won't mesh with the Hurd design well.

<nikolar>well apparently there is a (not entirely finished) fuse 2 implementation for hurd

<gnucode>nikolar: I'm guessing the "better" solution is to create our own specific filesystem that uses libdiskfs ?

<nikolar>yeah

<nikolar>my plan is for my fs to use fuse, but i want to make it as generic as possible since one of the later goals is porting it to a linux/netbsd kernel driver

<nikolar>and/or hurd
