People wanting lightweight stuff will use Busybox, so I think it's
fine. And as said on IRC, if someone wants to use login utils from
util-linux without PAM, then that someone should go upstream and fix

Ok, then I think I would really prefer to keep a single package.

The build takes:
on my laptop. It certainly builds and installs a bunch more crap than
