Hello.  This may seem like a silly question, but 
I see there's support for RAID controllers like the Escalade card in
NetBSD-current.  While I've read about the twe(4) and ld(4) drivers, I
don't see any reference to programs like raidctl which are used to define
raid sets, raid levels, and disk recovery operations on these cards.  How
are folks setting up raids on these cards, and is the plan to use something
non-obvious that lets you control the card before you start putting
filesystems on it?
-thanks
