I tried yesterday evening it on my laptop and on a ram-shrinked(256MB) rawhide
qemu/kvm-guest at home. At first it looked fine, but when the script started
to update with X11-stuff (perhaps due to their dependencies or so) it failed to
update with "Error: Failed to update:..."  the script tried the next one
and so on. After an hour I realized that both systems were no longer reachable
and continuously swapping.
This morning I have the following results:
- The laptop was dead and after a reboot it hangs (so it needs further forensic
   analysis ;-)
- The rawhide quemu/kvm guest is alive, but most of the 70 updates are failed
   when I believe the update script. /var/log/messages shows a lot of oom-killer
   activity. On first sight I think every failed update corresponds with at least
   one oom-killer entry...
