I made the small attached patch which creates the
kern.geom.allow_foot_shooting
sysctl.
It's no more than an explicit representation of the fifth bit of
debugflags (remember the famous value 16).
If needed, I would be pleased to make a modification to the geom(4)
manual page and also to drop a note about this in fdisk(8) and
boot0cfg(8).
Regards,
