I recently installed 9.1 on a system and labels don't seem to work as
I would expect. I can get them to work in /etc/fstab, but only the
ones referenced there show up in /dev/ufs and /dev/gpt. I have seen
this in previous versions, and in those cases they sometimes work. In
at least one previous case one ufs label (of several) would never work
even in fstab. The following shows my current configuration:

In this case I have two GPT labels defined, but only the one used in
fstab (BonsaiSwap) is shown in /dev/gpt and by glabel. When I used
the original fstab without labels, there were no /dev/gpt or /dev/ufs
directories, and glabel didn't show any of them.
Does anybody have any ideas about how to get the system to recognize
all labels? A command after boot would be acceptable since I could
just put it in /etc/rc.local.
I just discoved the sysctl 'kern.geom.label.debug=2' and did some
further testing. It appears that the system removes what it considers
redundant labels. For the Bonsai label it has labels for ufs, ufsid,
gpt, and gptid; so it removes the ufsid, gpt, and gptid labels after I
use the ufs label. The swap partition has gpt and gptid labels, and it
removes the gptid label after I use the gpt label. I don't really agree
with it, but I feel better about it now that I think I understand what
it is doing.
