The /sbin/raidadd and /sbin/raidrun binaries are missing. Result: using software raid is impossible (no fun when upgrading)
raidrun/raidadd are obsoleted by the new raidstart commands.
/etc/rc.d/rc.sysinit has references to raidadd and raidrun. These should be changed to the new names
this has been fixed in a later initscripts, available in Raw Hide...
