boot is the secondary boot-loader and is a file which should be copied
into the root directory as /boot
disklabel expects to be given the name of a file holding bootblocks
(primary boot-loader) which is eg. sdboot, xxboot, raboot etc. and
which are usually located in /usr/mdec/
bootblocks (or files holding images of these) have a special format
which has a gap (filled with zeroes) at a given offset. This gap
is at the same location as the disk-label on the disk. Thus the
disklabel program checks for the existence of this gap, which /boot
doesn't have and complains...
