Ok, the need for sysctl kern.geom.debugflags=3D16 arises because the live=

system to be used as master has mounted partitions, and those partitions
span the whole disk, thus conflict with gmirror which wants to use the
last sector. Since using the last sector for metadata is The Official
Way, how about making such conflicts easy to avoid, like for example
building additional logic in g_part to create partitions one sector
smaller than the container?
