BUGS
...
For the i386 architecture, the primary bootstrap sector contains an em-
bedded fdisk table. Disklabel takes care to not clobber it when in-
stalling a bootstrap only (-B), or when editing an existing label (-e),
but it unconditionally writes the primary bootstrap program onto the disk
for -w or -R, thus replacing the fdisk table by the dummy one in the
bootstrap program. This is only of concern if the disk is fully dedicat-
ed, so that the BSD disklabel starts at absolute block 0 on the disk.
Hence,
disklabel sd0 > /tmp/protofile
disklabel -B -R sd0 /tmp/protofile
should ``properly'' clobber the fdisk table.
