Not to mention that kerberos/ldap/nis/whatever might be down so user
logins might not be available.
In any case wouldn't it better to start using pam_access by default in
system_auth and block root logins if you want there? I don't see why sshd
should be treated differently than other tools in the system.
Anaconda, authconfig can ask questions at install time like:
Allow root logins: [X] Local, [] Everywhere, [] By domain ..., etc.
Allow user logins: [] Local, [X] Everywhere, [] By domain ..., etc.
and setup an access.conf file.
