// ...union directories are used hardly at all, and when they are,
// it's generally only in "special purpose" places...

for what it's worth, the lab i was in at BL did a fairly complete
overlay on top of 1127's file server with our own tree. as i recall
our /lib/namespace approached 350 lines. we were pushing hard on
what the kernel was expecting that file to do, and did run into
issues on occasion, but for the most part it just worked, and was
very nice to use in practice. obviously, we would've been SOL had
the kernel not allowed reading union directories.

if i remember correctly, one user even had a fairly complicated
additional overlay of his own as his home directory was split
between our own and 1127's file servers (and he managed to be a
huge user on both ;-).
