Since rev 1.502 of rc(8) it creates a /bsd.booted hard link. At the

end of rc we call reorder_kernel which creates a /obsd hard link to
the same kernel.
In the past obsd was only created when doing a manual make install in
the kernel sources.
There is no need for two backup hard links during boot, rearange the
kernel Makefiles to restore previous behaviour and thus stopping
reorder_kernel from scribbling over /obsd.

Makes muscle memory of some kernel developers work again: /obsd can
serve as a known good kernel; and there was much rejoycing...

Discussed at length with benno, rpe, phessler and tb at
p2k17.

Seems like a good idea to deraadt.

OK benno, phessler, rpe, tb
