Update of /cvsroot/othersrc/external/bsd/genraidconf
In directory ivanova.netbsd.org:/tmp/cvs-serv2114
Log Message:
initial import of genraidconf, an embryonic RAIDframe configuration file
generator, into opthersrc.
The genraidconf command constructs a configuration file for a RAID set.
It uses various pieces of information to construct a number of disklabels
for the RAID set component disks using disklabel(8), and a configuration
file for RAID frame itself, raid(4) producing a file as described in
raidctl(8).
It also can zero components before use, performs some basic sanity checks
on its inputs, and, in general, prepares the RAID set to the stage where a
newfs(8) may occur on it.
This utility is embryonic, since it needs much more testing. As such, it
must be considered experimental at this stage.
