util-linux is a random collection of Linux utilities

The stuff in the subdirectories mount, fdisk, disk-utils, text-utils,
misc-utils, sys-utils, getopt-* should be rather distribution-neutral,
and installing it does no harm.
On the other hand, the stuff in login-utils defines initial boot-time
stuff, things that are done in different ways by different distributions.
If you install it, your machine may not boot anymore.
No RPMs are provided - get yours from your distributor.
