Which is why I have this patch to sys/boot:

When doing a PXE netboot so NFS mounts versus something else like a RAID
controller which might not actually be used. This can end up with a
in use type error preventing me from initializing the RAID controller.
Sometimes (I forget if it is 4.X or 5.X) I'd get the RAID controller
mounted as root if it was valid.
Note this change would "break" people doing a PXE style FreeBSD Install
via the mdroot but for that the loader.conf on the FreeBSD install
images could have
vfs.root.mountfrom=md<?>
then they should be okay. I think this would be more correct then
the current scheme.
I would prefer this not have to be required to be set in the loader so we
can boot via EtherBoot which sets the root via the BOOTP_NFSROOT option.
FYI, is there any objection to this patch for now.
