 First question - why does it matter ?

 Second question, if it really does matter - if you use the current
svn version (with util-linux-ng) does it match what happens on current
fedora and open-suse ?  If not, what are they doing differently
(take a look at their spec files), and why haven't they persuaded
upstream to do likewise ?  I don't ask about what happens on RHEL
because it is usually old, and carrying a lot of patches to backport
various changes to older versions.

 Alternatively, maybe it's a change to 'top' - I'm not at all
familiar with looking for real-time priority in it.

 The general rule of the LFS-family of books is that we think the
package developers usually know what to do.  Sometimes, particularly
on pure64 builds, that isn't always the case,
