Well, the blkid library, specifically, was getting confused.  E2fsck
uses the blkid library to map LABEL= and UUID= references to device
names.

One thing that you might do for devices that are always present (which
generally means you're not changing them in your /etc/fstab often) is
to use a UUID= reference instead.  They are definitely less convenient
than labels, but they are also much less likely to cause confusion by
having duplicately labelled file systems.

Granted, no one wants to *type* "mount
UUID=9e132c06-1fd0-4bbd-ad06-5995a8f45b26"; they'd much rather type
"mount LABEL=websites".  But if the only place the a
UUID=... specification shows up is in /etc/fstab, it might be worth
it.

Then you can just zap the label on file systems that you only plan to
reference via UUID, and then that reduces the chances for confusion in
the future.
