bug#73547: Unable to run `guix pull` on Fedora (Asahi) due to SELinux violations

[Pasta Pasta via Bug reports for GNU Guix <bug-guix@gnu.org>]

Hi all,

I installed guix via
https://guix.gnu.org/manual/en/html_node/Binary-Installation.html
specifically
```
cd /tmp
wget https://git.savannah.gnu.org/cgit/guix.git/plain/etc/guix-install.sh
chmod +x guix-install.sh
sudo ./guix-install.sh
```

I then tried to follow the docs here:
https://guix.gnu.org/manual/en/html_node/SELinux-Support.html related
to SELinux

I ended up running
```
sudo semodule -i
/gnu/store/271mkw93sqb3hc4ngszcjfsc2wsb6yc8-guix-1.4.0/share/selinux/guix-daemon.cil
```

As this was the only file I found that looked right according to the
docs such as `semodule -i etc/guix-daemon.cil`

I've restarted my system a few times, however, I am still getting
SELinux violations resulting in
```
$ guix pull
guix pull: error: remounting /gnu/store writable: Permission denied
```

see the detailed SELinux violation report

```
SELinux is preventing guix-daemon from remount access on the filesystem .

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that guix-daemon should be allowed remount access on
the  filesystem by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'guix-daemon' --raw | audit2allow -M my-guixdaemon
# semodule -X 300 -i my-guixdaemon.pp

I tried running the recommended steps by SELinux, but that did not work.

Please advise!
