Hi there, is it likely to get System - Library - problems after installing
prelink on a up to date (which means new) gentoo system? is it good advise
to use it?

I'm having no problems (but no significant speed-ups) so far.
You can always revert all pre-linked binaries back to their original
state (check man prelink)

thanks a lot for your help!

Just to clarify things about what prelinking does:

It generates a binary (executable file) with all the necissary libraries already inside. This
means, if you prelink a file and then update one of its libraries, the prelinked file will NOT see
the changes until you re-prelink. There isn't really any (significant) danger to prelinking over
non-prelinking (in fact there may be less if you prelink, since you don't have to worry about
ruining lib files) but IMO its more of a pain than its worth since you have to re-prelink whenever
you update libs.

wrong :-)

$man prelink =>

DESCRIPTION
prelink is a program which modifies ELF shared libraries and
ELF dynamically linked binaries, so that the time which
dynamic linker needs for their relocation at startup
significantly decreases and also due to fewer relocations the run-
time memory consumption decreases too (especially number of
unshareable pages). Such prelinking information is only
used if all its dependant libraries have not changed since
prelinking, otherwise programs are relocated normally.

ehm... sorry... didn't read your reply twice and count to 100 before
answering (I really need to start doing that).
