Of course I tried that, and it did _not_ work! I'm not sure why, but it was
when running a 8.0-RELEASE userland on a 8.1-RELEASE kernel. (I was trying =
to
run 'make installworld' after booting in single user mode during the upgrade
process). After booting with the old 8.0 kernel it did work!

This is probably a better idea.
But people should note the difference between
using 'tunefs -L' and 'glabel label'! The latter uses the last section of t=
he
provider to store metadata, so in that case one should _only_ create a
filesystem on the labeled device!
