add a bootable UFS partition to a
||partition-letter isofile ufsfile|
mksuncd utility adds the file
ufsfile to the end of isofile.
ufsfile is assumed to be a bootable filesystem image
and isofile 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, and
mksuncd will update that label so that the partition
(a-h) given by partition-letter points to
ufsfile within isofile.
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.
