This is not very pretty, but the code in fs-util.c already provisions for missing /proc. We ourselves are careful to set up /proc, but not everybody is and it is important for sysusers to also work where shadow-utils would: I would like to replace calls to useradd and groupadd in Fedora systemd rpm scriptlets with a call to sysusers. It has a number of advantages: - dogfooding - we don't need to manually duplicate the information from our sysusers files to scriptlets - a dependency on shadow-utils is dropped, which transitively drops dependencies on setup and fedora-repos and bunch of other stuff. We could try to get 'dnf' and 'rpm --root' and such to be reworked, but not in any reasonable timeframe. And even if this was done, we'd still want to support older rpm/dnf versions.
