Kinda, except it's what is required for "FreeBSD" (for the definition
we are familar w/) to run...

After looking at */conf/DEFAULTS, we already have one other option for
this global include, device mem...  And you could argue that options
NEW_PCIB should be there too (or really, it just be turned on by
default now)...

Though why they forced you to remove GEOM_PART_BSD, but didn't remove
it from all the other DEFAULTS is beyond me...  arm is the ONLY one
that doesn't have GEOM_PART_BSD in it...  GEOM_PART is completely
unnecessary for a system to run since you can do NFS root...  So, the
argument that it is required for the platform to run is BS...

IMO, we should have a global defaults file which include a few standard
things..  For example, on really small systems, you might want to rip
out subsystems you don't want/need, so things like kqueue might be able
to be removed...

Back before config supported nodevice and nooption, it made sense to
only include required options, because there was no way you could turn
it off...  Now that we have nooption and nodevice, including the most
common for each platform in DEFAULTS is the way to go...  btw, include
was added in 2001, and two years later nodevice and nooption was
added...
