Hi, Thanks for the suggestion.
I stumbled on this guix rpm but it seems also that selinux needs to be
disabled with that one.
I think the maintainer initially wanted to apply selinux policies but in
the end commented out all those parts. (There's also a hint in the
changelog that it doesn't work with selinux, see here [0]).
As someone else suggested, yes I could set selinux to permissive but I
don't find that an acceptable solution. I don't want to disable a
security feature of my system.
Also an update on my initial email: after a reboot, I'm back at square
one with the remount error. So the solution wasn't really one.
Best regards,
Alexis

Hi,
I haven't tried the official guix installation, but I was
able to get guix running on Fedora using rpm packages from copr:

If you can't find solution to the SELinux problem, maybe
give those rpm packages a try.
Best regards,

Hi,
I'd like to try the guix package manager but am stuck installing it on
Fedora 38 with selinux. I should say I don't know anything about the details
of either guix or selinux.
I know a few other persons that also wanted to try guix but gave up due to
issues with selinux, so I think solving this issue could help in adoption.
I've used the installer script which worked well, then was initially hit by
this error
`guix install: error: remounting /gnu/store writable: Permission denied`
This was solved by doing
sudo semodule -i
/gnu/store/5kj8lyybjrdl7xd0fx9g9vzkz8sklqsy-guix-1.4.0/share/selinux/guix-daemon.cil
sudo mount -o remount,rw /gnu/store
sudo restorecon -R /gnu /var/guix
sudo systemctl restart guix-daemon.service
(note that the mount step was the missing part that was missing from all
guides I've seen on the web, and I found it in a guix commit).
Now I have a different issue, guix-daemon doesn't seem to be able to access
internet with errors of the type
`In procedure getaddrinfo: Temporary failure in name resolution`
(disabling selinux works in that case, but I want it enabled)
This is what I get from setroubleshoot:
```
SELinux is preventing guix substitute from search access on the directory
systemd.
***** Plugin catchall (100. confidence) suggests *****
*********************
If you believe that guix substitute should be allowed sea
rch access on the systemd directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this acce
ss.
Do
allow this access for now by executing:
# ausearch -c 'guix substitute' --raw | audit2allow -M my
-guixsubstitute
# semodule -X 300 -i my-guixsubstitute.pp
```
Trying the suggested commands also errors in:
```
libsepol.hierarchy_add_type_callback: guix_daemon doesn't exist,
guix_daemon.guix_daemon_t is an orphan
libsepol.hierarchy_add_bounds: 1 errors found while adding hierarchies
```
So I don't really know where to go from there, any help appreciated.
Thanks
Alexis
