Thanks.  I (at the /etc/fstab level) do use a label that goes with the
drive, mainly the lvm VG and LV names.  The problem is that the lvm
mapper *internally* must still use the name that the drive had when the
computer first booted.  It gets confused when the drive gets renamed at
runtime (long after boot).

Ditto.  I have my machine dual ported and I'd really like eth0 to be the
internal ethernet and eth1 to be the external.  (Some programs like
multicast progs seem to default to the first ethernet and it would be
nice for me not to spew packets towards the public internet.)

If the airwaves belong to the public why does the public only get 3
non-overlapping WIFI channels?
