Maybe I'm being blind here, or just plain dumb - but I cannot
seem to get union mounts working on my NetBSD/sun3 (NetBSD/i386
works fine).
Both have kernels with options UNION, but the PC likes
mkdir /tmp/mount ; mount_union /tmp/mount /usr/share/doc/
while the sun3 complains
mount_union: Operation not supported
for the same command...
Is there something obvious I'm missing? (help! :)
