>Description:

I just updated two machines booting from raid 1 from older installations
and now am unexpectedly asked for the root device on both.
A 9.88.80 kernel did boot w/o prompt.

Also note that the raid cloned itself, raid1 is a fake.

State-Changed-Why:
At least the 'configure two times' is fixed.  This will likely (hopefully) also fix the 'does not autoconfig root' part of this PR as well.

Subject: PR/56369 CVS commit: src/sys/dev/raidframe
Date: Sat, 28 Aug 2021 16:00:52 +0000

 Module Name:	src
 Committed By:	oster
 Date:		Sat Aug 28 16:00:52 UTC 2021

 Modified Files:
 	src/sys/dev/raidframe: rf_netbsdkintf.c

 Log Message:
 If there is a FS_RAID partition on a disk, then we shouldn't look at
 the raw partition.  In particular, we now need to account for the case
 where an existing FS_RAID partition is now open because it is in use.
 If that is the case, we don't look at the raw partition.

 Addresses PR kern/56369.
