I've found that it is a good idea to find concepts and implementations
 that weren't very well thought out before they bite you somewhere, so
yes, I do go out of my way.  For example when mounting by label was
first implemented, having a duplicate label (very likely if you move
disks around at all since the installer always used the same labels)
would keep the system from booting at all.  You had to just say 'what
were they thinking...' - and wonder about the rest of the system.

To what?  It's something that is going to hold some data in the
future.  And you may not know you need to re-mount it until the
machine that labeled it is gone or dead and the drive is all that is
left.

Within 5.x I've found auto-assembled md devices to be pretty reliable
at identifying themselves, but booting the 6.x livecd completely
messed that up on the one machine where I tried it.
