I've installed Guix and installed the bundled SELinux policy manually. But according to Ricardo Wurmus, as of 30 June 2021:

There are really just two ways: either 1) disable SELinux (or set it to permissive mode) or 2) install/debug/reinstall the SELinux daemon policy that is included with Guix.

The daemon policy is not installed with the binary installation method because it is known to be incomplete. You would need to get a copy of the Guix sources and configure it. The file you want is called “etc/guix-daemon.cil”. To debug it you would need to install it, set SELinux to permissive mode, run the daemon, and then check the audit log for errors.

There is an open issue for SElinux guix-daemon.cil file, which suggests a patch that seems already incorporated in the file bundled with my installation.

I installed setroubleshoot and kept restarting the guix-daemon.service while following the suggestions popping up in notifications. The daemon finally started after:

$ sudo chcon -R -t guix_daemon.guix_daemon_conf_t /var/guix/
$ sudo chcon -R -t guix_daemon.guix_profiles_t /var/guix/profiles/per-user/root/current-guix
$ sudo chcon -R -t guix_daemon.guix_profiles_t /var/guix/profiles/per-user/root/current-guix-1-link

But I still cannot proceed with installing glibc-locales:

$ guix install glibc-locales
hint: Consider installing the `glibc-utf8-locales' or `glibc-locales' package and defining `GUIX_LOCPATH', along these lines:

     guix install glibc-utf8-locales
     export GUIX_LOCPATH="$HOME/.guix-profile/lib/locale"

See the "Application Setup" section in the manual, for more info.

guix install: error: remounting /gnu/store writable: Permission denied

The SELinux diagnostics tool informs that "guix-daemon" is not allowed "remount" access to "filesystem" and suggests:

# ausearch -c 'guix-daemon' --raw | audit2allow -M my-guixdaemon
# semodule -X 300 -i my-guixdaemon.pp

But ausearch fails on this:

$ sudo ausearch -c '(x-daemon)' --raw | audit2allow -M my-xdaemon
compilation failed:
libsepol.hierarchy_add_type_callback: guix_daemon doesn't exist, guix_daemon.guix_daemon_conf_t is an orphan
libsepol.hierarchy_add_bounds: 1 errors found while adding hierarchies

How can I allow guix-daemon to remount the filesystem in SELinux?

I turned on the permissive mode and used Guix for a while. SELinux support is apparently still a work in progress. setroubleshoot regularly notifies of various issues. Running Guix with SELinux in permissive mode seems the only practical solution at the moment.

(To turn on the permissive mode permanently, edit /etc/selinux/config and reboot.)
