:Hmm. Isn't the only thing that's suppose to really work is
:
:dd if=/dev/zero of=/dev/da0 count=16
:
:(which doesn't always work on Alpha yet)

:I'm missing some context, so forgive me if this is a stupid question?
Ah, the joys of fdisk and disklabels. I've learned more in the last
two days then I ever really wanted to find out :-)
# clear out feldercarp at the base of the
# disk and create a real slice for freebsd. Install
# the MBR.
#
dd if=/dev/zero of=/dev/da0 count=16
fdisk -BI da0
# clear out feldercarp in the slice and then disklabel the
* slice (using my patch) + the boot blocks
#
dd if=/dev/zero of=/dev/da0s1 count=16
disklabel -w -r -B da0s1 auto
Presumably a '-z' option to disklabel would do the equivalent of what
the 'dd' in the above examples are doing.
