I would like to update my boot blocks on my IDE (probably a Western
Digital) /dev/wd0, but apparently my disklabel is not good. If I
try
disklabel -B -b /boot/boot1 -s /boot/boot2 /dev/rwd0
I get
disklabel: bad pack magic number (label is damaged, or pack is unlabeled)
Can I get a proper disklabel on the disk without hosing the filesystems?
(I do have a tar backup from last night, but I'd like to avoid using it.)
Many thanks.

P.S. Please respond with e-mail; I track -current, but not -questions.
P.P.S. This is 3.0-current, cvsup'ed nightly (I just did a make world
this AM). I also made a boot floppy and test kernel, and that
loaded correctly (up to panic: no init, of course ;-)
P.P.P.S. Some info from the system:
