Oh, THAT.

That stuff only uses the MBR to find the NetBSD partition on the raw
disk or to totally wipe it out (if there is no NetBSD partition) it
doesn't usually touch it in any way. I don't believe I've ever even
seen the wipeout code invoked! You have to fuck the machine pretty
badly to have that happen -- or try to label a disk you haven't used
fdisk on first!

However, disklabel has nothing to do with altering the contents of the
MBR -- it doesn't set MBR partition sizes or types, ever. It knows
nothing about such stuff.
