Wow! Last time I saw this was on EAW's WEGA (a UNIX System III
compatible UNIX developed in the GDR for the P8000 workstation).
There even was /etc/mount and /etc/fsck. :-)

These two lines illustrate the different use of the results
of "glabel label" for generic labels and "tunefs -L" for UFS
labels very well.

A really honest question: What does the "p" in "ad10p1"
indicate? I always thought swap partitions are something
like "ad10b" (an own partition right after the root
partition a).

Why make a label available for something to mount that is
already mounted and cannot be accessed through this label
while being mounted? :-)

The kernel messages show such messages about removing labels
as soon as devices are mounted in the "traditional" way.
