7 Usually things turn ugly - used to be that portage saw that there are
8 two glibcs installed and unmerges one (oh crummy, you only had one?
9 better reinstall now ...) and other really disturbing side-effects.

11 Just unpacking a stage3 over a live system is a nice game, but rarely
12 has sane results. You'd need to use a VDB-aware tool like qmerge to do
13 it cleanly, and then you still don't have a working system (new glibc on
14 old kernel, new udev on old kernel, lots of situations where things
15 don't work out)
