Nope, it was a clean BETA3 installation with the default GENERIC kernel
which has afaik geom_label in kernel, but not geom_mirror (nevertheless I
loaded geom_label.ko at boottime as well as geom_mirror)
The same with RC1 - clean and fresh installation with the default GENERIC
kernel and geom_label in kernel (default), but still loaded as module at
boottime as well as geom_mirror.

This makes gmirror+glabel work again on RC1

One thing which I noticed. I labeled in single user mode, my root
partition with tunefs - as well as all my other partitions. After this
was done, I remounted my root partition (mount -rw /) and changed my
fstab to use the new geom labels instead. But somehow this "killed" the
new root-label of my mirror/gm0s1a partition. After I rebooted, the label
was gone and I had to manually specify the root partition
ufs:mirror/gm0s1a to mount. All the labels of my other mirrored
partitions where there (usr, tmp, var). I then rebooted once more into
single user mode (specified once more the root partition manually) and
did a tunefs -L once more. Then I rebooted directly and the label is now
there.

Is it possible that mount -rw / (which remounts /dev/mirror/gm0s1a) could
have been killed the freshly given label?
