This was erroneously added to overly broad class of images.

It was dropped from make-initrd back in 2012:

filesystem package has been severely broken in sisyphus
since late August unfortunately, and I was too busy to
even notice that for too long; let's plug this kludge
until it's fixed now that I've finally seen that crap :-/

The issue at hand it _nmconnect group that's supported
in ALT NM for polkit-less cases; it has to be added
*before* 50-users hook from deflogin feature fires off.

The existing systemd-related hook has been renamed
to reflect its job better.

This one is finally there and should help reduce the
systemd-induced mess in package lists and specifications.
