I just cloned the 5.6 install, and it worked.

Well, kinda. You may have seen, or missed, the thread a couple weeks ago,
about this: we do have a local repository, and comps.xml was missing.
Then, having now switched to my new workstation, I found that window
manager names changes (like KDE and Gnome), so they weren't installed, and
for some reason, xorg was not a prerequisite. OO.o, btw, has had a group
name change as well.
