you don't really need to soft raid the boot partition, since you can just put
it on both physical disk, and set the system to boot from either, with
something like this:


ok> setenv boot-device disk0 disk1


/pete

fine so I compile and install a new raidframe-enabled kernel.  Rebooting again
produces many core dumps - `uname -a` says 4.6, but the filesystem is from the
old 3.9 raid - the new raidframe kernel must have found the raid set on the
2nd disk.  Physically ejecting the second disk (sd1) and rebooting gives a
clean boot, but now, of course, I don't have the second disk to install the
raid set on...

compile/install 4.6 on top of a raidframe set avoiding the need to reconfigure
it at all?

realizing that it didn't support raid on the root disk.  This was especially
confusing as its man page lists "softraid0 at root" while not specifically
saying that it doesn't support raiding the /root disk.  Maybe the FAQ and man
page could be more clear on these points?
