Serious question: why usrmove is not doable?
If you have all the dirs in your path, and move executable files from one
place to another, why should this fail?

I managed to do a 32 bit -> 64 bit transition (you know, the "absolutely
unsupported" upgrade) on a system which was running an entire KDE session.
My upgrade commands (rpm, yum, bash, everything else) started 32 bit,
then were mixed, then ended to be 64 bit.
Usrmove appears simpler. Am I missing something?
