No, it didn't absorb revdep-rebuild.  It just does early (live)
detection.

Actually, with the new python version of revdep-rebuild, there was talk
of it absorbing python-updater and perl-cleaner (also coded in python)
as part of it's normal revdep call.  Then it would be a one stop call.

Actually, I think in this case. the original error would have been
avoided if the user had used the same snapshot for all stages of the
build.  stage1 through livecd-*.  I believe he/she just grabbed a stage3
and a current tree snapshot.

We could however change catalyst to accept a stage3 and perform an
update, perl-cleaner, python-updater, revdep-rebuild,... before
commencing with the build process, but I feel that is a step better done
by hand.  It would also need to wait for catalyst to move to using
emerge/portage through the api.  From there it could get the list of
atoms to be updated and handle any calls on an as needed basis to
perl-cleaner, etc..  That would also require me to complete the
public_api work I was doing for portage.
