So it won't work on Debian? I think Debian and Fedora uses different
base policy, right? If this is the case, should we also include an
apparmor profile? Which paths does guix-daemon need to have r/w access
to? From your SELinux profile, we know the following is needed:
@guix_sysconfdir@/guix(/.*)?
@guix_localstatedir@/guix(/.*)?
@guix_localstatedir@/guix/profiles(/.*)?
/gnu
@storedir@(/.+)?
@storedir@/[^/]+/.+
@prefix@/bin/guix-daemon
@storedir@/.+-(guix-.+|profile)/bin/guix-daemon
@storedir@/.+-(guix-.+|profile)/libexec/guix-authenticate
@storedir@/.+-(guix-.+|profile)/libexec/guix/(.*)?
@guix_localstatedir@/guix/daemon-socket/socket
Also, access to $HOME will also be needed. What else?
