I'm not so sure they are... perhaps it's time for another round of 'how
fast does libreoffice start when prelinked vs not'?
after these dicussions i tried it again these days multiple
times witout and with "prelink -mRa"
the possible difference is snake-oil
on fast machines it doe snot matter
on small machines AKA notebooks the prelink-cronjob did hurt
me all the years way much more as it brought benefits and
the fact that you get neraly each day some updates which would
make prelink necessary and bring rkhunter to whine and defeats
at least the benfit of any IDS is a very strong indication to
leave it in the repos for people who feel better with snakeoil
but do not enforce it as default
