Protection mechanisms in the geom(4) subsystem might prevent boot0cfg

temporarily disabling these protection mechanisms can be found in the
geom(4) manpage. Specifically, do a
sysctl kern.geom.debugflags=0x10
to allow writing to the MBR, and restore it to 0 afterwards.
This is stale message. boot0cfg might work without this.
On a *mounted* disk? Surely that qualifies as an "open" for the purposes
of the check.
