I am totally in accord with these sentiments. My `universe' includes
macppc *AND* the dreaded i386. I don't want the macppc port corrupted
by i386 `fixes'. Or vice versa.
As author of PR 7950, dated Jul 1999, I supplied a patch to have
the kernel construct a BSD disklabel from the MBR&c stuff, *in the
absence of a NetBSD label*. What the patch effectively said was:
``don't ever run disklabel(1), let the kernel build it every
time you boot from an MBR disk on i386. Let it find your extended
or changed partitions, just as *choke* DOS would.''
In other words, the concept is that the MBR stuff is authoritative
in the i386 world *in absence of a BSD label*, and that the BSD
label should be constructed at boot time. Stated a bit differently,
you shouldn't have to supply redundant, and possibly conflicting,
information for the partition table. Just use the MBR on i386. Period.
