/etc/cron.daily/prelink
starts with renice +19 -p $$ >/dev/null 2>&1

I totally agree with Roland, this should be solved in cron. When a new
category for run daily when the system is most idle or something like
that is added, I'll certainly move prelink to that category.
(and slocate.cron should fall in exactly the same category).

But, even current prelink cron job, if there are no changes
on the system it shouldn't do too many disk accesses nor take much CPU time.
