You missed my point.  I'm talking about the question of "what happens
if the upgrade is interrupted".  I'm saying that the situation 
should always be recoverable by running the upgrade again (yum,
apt, anaconda, whatever).  I never said that the half-upgraded
system would be bootable or functional, so getting to the point
of using yum or apt to fix it up could be tricky :-)
