>Description:
	I have several raid volumes which do not autoconfigure for
	whatever reason, so I need to start raidframe.  Might have had
	something to do with having higher-number raid volumes as sub-raids
	of the lower number (raid2 == raid20 + raid21)?  I don't know.
	That, in and of itself, is an annoyance I will probably just have
	to live with.
		-
	When my system restarted, the lvm rc script ran _before_ raidframe
	did.  I would expect that more people have LVM atop RAID than the
	converse, so I patched /etc/rc.d/lvm to require raidframe before
	attempting to configure the volume groups.
>How-To-Repeat:
	* set up a raid device (raid 1 + 0: 2 mirrored pairs, striped)
	* set up config files for them in /etc.  Set autoconfigure to 'yes'.
	* Start slicing the RAID up into PVs, and allocate VGs and volumes.
	* enable lvm and raidframe in /etc/rc.conf.
	* reboot the machine.
	* If your raid devices come up fine, well, this exercise is
	  pointless.  I tried...(try again with autoconfigure to 'no').
	* Notice that lvm runs before raidframe.
