This patch works better.
This brings us back to the original problem :-)
Now it doesn't panic during fsck immediately, it panics after unconfiguring
the md(4) device (which leaves the /dev/md11* devices in place instead removing
them) reconfiguring and then doing a new `disklabel ...` which tries to do
a (still existing) new 'make_dev("md11s1")'....
See the attached backroot.sh.
Bye!
