i was gonna parry with

	install -crb netbsd /netbsd

but it seems that (a) install does a rename(2) to the backup name
first, and then a rename of the newly installed file to the target,
(b) there's no easy way to get it to rename it to onetbsd instead of
netbsd.old, and (iii) there's a bug in kdump that causes it to segv on
reading the ktrace file that i used to come up with (a) and (2).

send-pr coming up.  :)
