Changing RAIDframe "Last configured as"

[Stephen Borrill <netbsd%precedence.co.uk@localhost>]

Just ran into RAIDframe endeavouring to keep device numbering constant 
when auto-configuring (which I don't remember it doing before). For 
example, I'd created a RAID-1 on raid0 on a lab machine to save rebuild 
time when doing a later installation and then added these drives to an 
existing system which had raid0 as root (plus raid1 as swap and raid2 for 
data). It decided to configure the new RAID-1 as raid0 and renumber the 
others to raid1-raid3. Similarly, I had a second system where I was 
copying to newer hardware and temporary put the old HDDs in the new system 
(which configured them as raid4-6). I then wanted to boot from the old 
HDDs back in the old system, but the raid4-6 remained persistent.

I couldn't see an easy way to reset the "Last configured as", I was 
looking for a raidctl subcommand. Did I miss something?

My workaround was to boot from USB, dump the configs with raidctl -G, 
unconfigure the incorrect-numbered devices and re-configure from the 
configs on the correct device number.
