Subject: union mounts seem to work
Sender: owner-current@freebsd.org
X-Loop: FreeBSD.org
Precedence: bulk

I had few problems building part of the tree using union mounts:

	cd ~					# ~ happens to be nfs-mounted
	mkdir a
	mount -t union -o ro /usr/src ~/a	# /usr/src is also nfs-mounted
	mkdir /tmp/obj
	mount -t union /tmp/obj ~/a
	cd ~/a/bin
	export MAKEOBJDIRPREFIX=		# use objdir = curdir
	make					# failed, src dirs are owned
						# by root although they are
						# by bde in /usr/src, and they
						# were originally non-statable
	su
	make					# worked
