add a bootable UFS partition to a filesystem image
utility adds the file
to the end of isofile
is assumed to be a bootable filesystem image and
is assumed to be something like an ISO 9660
filesystem. A Sun-style disklabel is expected to already be present at the
beginning of isofile
will update that label so that the partition
(a-h) given by partition-letter
Based on the label in isofile, that file is
padded so that added files are always on cylinder boundaries. This is a
requirement of the PROM.
This program is not endian or type safe. It makes several assumptions about both
based on its SPARC bias.
