Subject: Broken system and home containers
Date: Sat, 10 May 2025 18:09:24 +0200

Seems that the recent commit 'Lock mounts by default'
a57ed987ffd1452ba5a4d70feb54893e99b8e076 has broken both guix system
container and guix home container. For system container, the system
container command finishes fine, but then running the run-container
script fails. For home container the command itself errors out, since
it's what is starting the container as well.

Here are the backtraces:
guix system:

Additionally at one moment I was able to get an error message with guix
home that unshare has gotten an invalid argument, the argument was just
a number.

Unfortunately I was not able to understand what the issue is to fix it.

For home, I tried my own config, and since I was pretty sure any system
container is affected (tried a simple one, my one and I know one other
person reported this in Matrix channel), I didn't try anything simpler
and just assumed all homes are going to be affected as well.
Now trying simpler config you mentioned, that one works fine.

The command was `guix home container -L ./home/modules ./home/home-container.scm`
in my repository. It's here https://git.ditigal.xyz/~ruther/guix-config.
Any idea what service could cause this behavior with lock-mounts? Would
be good to isolate it, but I am not sure where to start.

Here is the unshare error I was talking about earlier:

Could you copy paste the command and its output, to be sure there’s no
misunderstanding?

This is on Guix System, right?

Is this from within a container?

Does ‘guix shell -C coreutils’ work?

No.

Yes, shell containers work fine for me, it was just home and system
where I saw an issue. As I pointed out earlier the home container in
guix source tree works for me. So it's triggered by something in my home
setup.

What’s weird is that this seems to happen even before activation.

I cannot audit the whole thing but apparently something in the config
tries to connect to the outside:

--8<---------------cut here---------------start------------->8---
<x home container -L home/modules home/home-configuration.scm

web/client.scm:338:10: In procedure open-socket-for-uri:
In procedure getaddrinfo: Servname not supported for ai_socktype
--8<---------------cut here---------------end--------------->8---

Probably use of ‘current-guix’?

Anyway, do you think you could boil it down to a minimal reproducer?

Thanks,

So this is after the build? I have added inferiors recently for using
Emacs 30, that would explain it before build, but after build I am
clueless why that would happen. Though if it's before build, I am
surprised you got an error like that, unless you were purposefully in
environment without network. I added the inferiors just yesterday,
commit 819ee341ab6bcc9846b099572af185c781b82a1d shouldn't be downloading
anything.

I will definitely try to, but probably not today, in a few days,
hopefully by the end of the week.

Yes, I was running it in ‘guix shell -CW’.

Not sure how minimal that is, but I can trigger this in the readymedia
system test:

--8<---------------cut here---------------start------------->8---
make check-system TESTS=readymedia
--8<---------------cut here---------------end--------------->8---

It may not fail every time (?).  In the VM, in
/var/log/readymedia/minidlna.log, we can read:

Damnit.  “make check-system TESTS=bitlbee” pass though (also using
‘least-authority-wrapper’) and I don’t see any significant difference
between the two?

I'm getting this "unshare: 268566528: Invalid argument" error just

a local Haskell package today, and I think it might be relevant to 
this bug.  Here is the backtrace:

What I did is basically the following things in order (I believe 
only the manifest is needed to reproduce):
1. `guix shell -C -m manifest.scm`
2. then I attempted `cabal build` but I realized that now I need 
writable root.  So
3. I quit the current shell and then `guix shell -C -m 
manifest.scm --writable-root`, it failed with the above error.
4. After that, `guix shell -C -m manifest.scm` also failed, but if 
I kept retrying sometimes it succeeded.  With `--writable-root` it 
failed consistently.

Output of `guix describe`:

I had been using Guix at the commit 
`d505cb960fd1e670be9a66d9fdbad94bc49e891d` before yesterday (so 
`--writable-root` were not introduced yet) and I had never got any 
similar error before.  I hope my case is reproducible ;)

Thanks,

I can confirm I can get this with your manifest as well. But not
consistently, I have to rerun the shell container multiple times to get
it. Also, from simple trial it seems it's the development inputs of
xmobar-hiecaq that cause this. I am not getting the issue when I comment
everything else in the manifest. But I haven't tried minimizing this
even more to a specific input.
