/etc/rc.d/rc.sysinit uses the older raidadd and raidrun commands. These commands are not included with the 6.0 distribution. In fact, they have replaced with the newer raidstart program (in the raidtools package). It is impossible to have raided filesystems mount at boot time with the commands currently in rc.sysinit.
