Updated such that role scripts all live in one directory, regardless of
the distribution to which they are meant to be applied.
This role directory can be specified with "--roledir", or via the configuration file setting "roledir=/path/to/dir".
See the following bug for rationale:

Simplified 60-copy-host-files to only copy file(s) from the host
and install SSH (not gentoo yet).
This way we can move the /etc/passwd handling to a new file.
When setting up the new Gentoo system allow *all* users to 'su' to root.
This is pretty mandatory if you've copied accounts over, but root logins
are disabled.
