Several flags are provided for tracing GEOM operations and unlocking pro-
tection mechanisms via the kern.geom.debugflags sysctl. All of these
flags are off by default, and great care should be taken in turning them
0x10 (allow foot shooting)
Allow writing to Rank 1 providers. This would, for example, allow
the super-user to overwrite the MBR on the root disk or write ran-
dom sectors elsewhere to a mounted disk. The implications are
There should be several partition editors in sysutils/*, so the only thing you
really need is to set kern.geom.debugflags to 16.
A quick scan of gpart(8) man page might have support for logical paritions,
but I'm not an expert:
add Add a new partition to the partitioning scheme given by geom.
The partition begins on the logical block address given by the
-b start option. Its size is expressed in logical block numbers
and given by the -s size option. The type of the partition is
given by the -t type option. Partition types are discussed in
the section entitled "Partition Types".
Problem with today's modular software: they start with the modules
and never get to the software part.
