This is no different to hard coding a value in /usr/src/etc/group
anyway. All "make distribution" does it copy the source file directly
The problem I see is that we are shipping the usermgmt tools as part
of the base OS for the first time for 1.5, and the default group for
useradd is "users". On an upgrade, someone is not likely to have a
group called "users" and when they go to use useradd - boom.
What if the default group for the usermgmt tools was changed to "guest"
instead? The other option is to fall back to "guest" if "users" doesn't
