I then loaded the profile with "sudo apparmor_parser -qr
/etc/apparmor.d/guix-shell-container".  "guix shell -C hello" and "guix
shell -CN hello" worked fine.

To refine this policy I used the following process:

1. run "sudo aa-genprof guix" in one terminal
2. run "guix shell -CN hello" in another
3. update /etc/apparmor.d/guix-shell-container as needed (often
replacing temporary directory names with glob patterns)
4. repeat

We may want to create a template file in which we replace all instances
of /gnu/store and /var/guix with their respective configured values and
install the file in the same manner as we do etc/guix-daemon.cil.

I wonder if we need to provide something similar for SELinux where we
only have the guix-daemon policy.

Hi Ricardo and all,

Ricardo Wurmus <rekado@HIDDEN> skribis:

This issue is informally reported quite frequently these days.

Can someone on Ubuntu having this problem confirm that it works for
them?

And then, bonus points if you can create a patch against Guix that (1)
adds the file above under etc/ in the source tree, and (2) changes
=E2=80=98etc/guix-install.sh=E2=80=99 to perform the above setup step on Ap=
parmor
distros, similar to how SELinux is handled.

That=E2=80=99d be a much appreciated contribution!

Thanks,
Ludo=E2=80=99.

Hello to all,

I confirm the issue on my Ubuntu 24.04 installation with Guix coming from apt 
repositories.

I followed the steps from the Ricardo's reply, but the problem persists with the 
same error:

```
guix shell: chyba: mount: mount "none" on "/tmp/guix-directory.DFemEr": Prístup 
odmietnutý
```

Note that in the above message 'Prístup odmietnutý' means 'Access denied'.

Have there been any new developments regarding this issue?

PS: My current Guix generation is based on the commit c3290ce of the official 
Guix channel.

Thank you very much!

Best regards,
Marek

No!  I guess Ricardo was on the right track but this probably needs more
testing and polishing.

Is there additional info you can get by running =E2=80=9Cdmesg=E2=80=9D or =
something
like that?

Thanks,

Hi Ludovic!

I ran the following Guix command

```
guix shell -C bash -- bash
```
and got these two entries in `dmesg` log.

```

```
Is it of any help? Is there something else I should have a look at?

Thanks,
Marek.

Hello!

I believe the attached AppArmor profile should work.  You need to:

  1. Drop it in /etc/apparmor.d/guix (it=E2=80=99s actually not specific to
     =E2=80=98guix shell -C=E2=80=99 since it matches any =E2=80=98guix=E2=
=80=99 command!).

  2. Run =E2=80=9Capparmor_parser -rv /etc/apparmor.d/guix=E2=80=9D.

And then you can check =E2=80=9Cguix build whatever=E2=80=9D and =E2=80=9Cg=
uix shell -C hello=E2=80=9D.

Note that AppArmor is stateful: it memorizes previous rules (=E2=80=9Cprofi=
les=E2=80=9D)
and it=E2=80=99s not entirely clear how to remove them, especially when the=
re=E2=80=99s
no profile name.

So perhaps you=E2=80=99ll want to reboot if in doubt.

Anyway, I tested it in an Ubuntu 24.04 VM and everything seemed to work
well.

If you can confirm, we can add it to the repo and have =E2=80=98guix-instal=
l.sh=E2=80=99
install it.

Ludo=E2=80=99.
