Comment # 13 on bug 1006978 from Franck Bui

Even though there's some conflicts with basic.conf on SLE12, it doesn't seem to
hurt and cause real issues.

So the plan, as discussed with Thorsten, is to do the cleanup on Factory only
since we can take advantage of the new user/group scheme [1]

Therefore for Factory, systemd will stop shipping basic.conf and will rely on
system-sysusers for the initialization of the basic system users/groups.

Udev in its turn will "Requires: system-group-hardware" to make sure that all
groups it uses will be created before it's installed.

I hope that makes sense.
