This is sort of what I thought of (of course you brought it into
detail), but I didn't know if there is maybe a better way, or if there
is actually a way to do this after the installation and not in preinst.
But I guess if nobody comes up with something better this is the way to
do it.
Maybe sth. like elog, just you don't log a message to summary.log, but
you log the revision of the package.
(Meaning, that you can use elog in every phase of an ebuild.)
