A couple Shadow versions ago, there was a patch I think in the CLFS book
to fix a few issues - one was to alter useradd and groupadd to reduce
the restrictions on user and group names - I've attached the patch here.
As I said, this was a couple versions ago so most of the issues in the
patch have already been fixed in the latest Shadow version, but the
restrictions on user and group names are still there, so the first bit
of that patch can still be applied if you want.
It's not really a problem for me since I just use the package name in
all lower case (yeah, I use package users too) - my only issue has been
the maximum length of user/group names, though in recent Shadow versions
that can be changed with a configure switch - I add
--without-group-name-max-length to Shadow's configure command.
