Log message:
Prevent detaching the boot volume
bioctl(8)'s -d has no sanity checks and happily "deletes" any volume,
whether currently in use or not.
For now, refuse to detach the boot volume as a (too) simple safety guard,
until proper logic around mounted file systems on top is implemented.
Found the hard way through "bioctl -d sd1" with sd1 hosting /, after which
it took both fsck(8) and installboot(8) from a miniroot USB to recover.
regress/sys/dev/softraid also triggers it if root is on softraid.
OK claudio op jsing
