Script to make a file system image (usually .iso) bootable by Sun
computers, by appending appropriate boot file systems to the image and then creating a disklabel using sunlabel(8). Inspired by distrib/utils/mksunbootcd, except that this is a shell script instead of being a C program that would have needed to become a host tool.

|

Usage: ${PROGNAME} fsimage sun4 [sun4c [sun4m [sun3|sun4d [sun3x|sun4u]]]]
|
||||
Combine file system partitions for Sun Microsystems, Inc. computers
|
||||
into a CD-ROM file sytem image suitable for booting on the
|
||||
following platforms:
|
||||
NetBSD/sun3: sun3, sun3x
|
||||
NetBSD/sparc: sun4, sun4c, sun4d, sun4m
|
||||
NetBSD/sparc64: sun4u
|
||||
The architecture arguments must be bootable file system image
|
||||
for that architecture, or \`-' if no entry is desired.
|
||||
\`fsimage' is typically an iso9660 file system image, although
|
||||
any time of file system can be used as long as the first 512
|
||||
bytes of the image are not used. \`fsimage' is modified, and
|
||||
the additional partitions are added in order. If the same
|
||||
filename is used more than once for different architectures,
|
||||
it will only be copied once.
