Subject: [PATCH] Exit gracefully if we are disabled systemwide

Sysadmins might want to disable any kind of initial setup for their
users, perhaps because they pre-configure their environments. We
should provide an easy way to do it.

At least the anaconda installer provides an option to skip any kind
post-install setup tools so, for now we're only adding support for
that but more might be added in the future.
