Yes, drive detection may change between alpha and beta. It could change
depending on the phase of the moon.
Device names are dynamically assigned and may change without warning or
reason. DO NOT RELY ON THEM STAYING THE SAME BECAUSE THEY WON'T.
This is why we use filesystem labels, UUIDs, etc.
and mac addresses for NICs.
While there may be a passing resembelance of Linux device names to
what you think a device should be named based on how you plugged in
various cables, don't expect those to stay the same or be consistent.
Doing so, you _will_ get bit some day. Use characteristics intrinsic
to the device itself (labels, mac addrs, ...) rather than some
perceived topology, and you'll be much happier in the long run.
