I don't if anybody is interested in an initscript to start software raid
services, but I have written one. I'd be interested in feedback.
the initscript uses raidtab to id the raid devices, it assumes that
fstab has an entry for any devives and if the module for the hostadapter
needs to be loaded, it sould be in modules.conf as raid_hostadapter*.
One thing I know it won't handle is stoping if the mounts are nested
(eg. /dev/md1's mount point is on the filesystem mounted on /dev/md0),
or starting if /dev/md0 is mounted on the /dev/md1 filesystem.
PS. if parts of this look familiar, I started with the alsasound
initscript.
