So, the RPM guys wanted a full tree in /usr/share, where they can put
both etc and var stuff. Kay and I are pushing for /usr/share/factory/etc
and /usr/share/factory/var hence. So to make a step here we now added a
logic to tmpfiles to automatically copy/symlink thing from
/usr/share/factory, if you use C or L in the files but don't specify a
source path. This means, simply putting this in a tmpfiles line will now
do the right thing if you put your resources in /usr/share/factory:

    C /etc/pam.d
    C /etc/dbus-1

These lines will initialize /etc/pam.d and /etc/dbus-1 from
/usr/share/factory/etc/pam.d and /usr/share/factory/etc/dbus-1.

Hope this makes sense.
