I've just had a look and this init script is bogus! The next time you run
insserv (i.e. installing/updating/removing a package with init script) the
runlevel links will be reset. Since 9.1 you should use LSB conforming init
scripts if you want things to work correctly.

At the end of the mail (because attachments aren't allowed) are apatch for
the RAIDMon install script plus an init script that should work correctly on
SUSE Linux. Just change to the raidmon directory, apply the patch with
'patch -p0 -i install.patch' and then call './install -suse'.

Note that I haven't tested it!
