Get rid of the raidtools that shipped with RedHat. Then remove all reference to
RAID in /etc/rc.d/rc.sysinit and /etc/rc.d/init.d/halt. Then get hold of the
raidtools 0.90 source, and compile that. Kernel - 2.0.38 doesn't exist :-). I
suggest using a clean 2.0.36 source tree, and patching that for RAID support.
Don't use the kernel source provided with RH 5.2, it's a 2.0.36 pre release,
with lots of weird patches added. Compile, and enable RAID-autostart. Then,
use fdisk to change the partition id's of the partitions making up your RAID
devices to 0xfd. After this, the kernel will auto-start and auto-stop your RAID
devices at boot and shutdown. You will not need any support in scripts at all.
