Bug 17386

	If extended file flags are set on the mtree files in /etc/mtree,
	pkg_create cannot remove its temp files, because of how pkg_create 
	copies the mtree file to /var/tmp.  It exec's cp(1) with '-p' 
	which preserves the flags as well as the usual file metadata.

	Since the only files that are copied in this way are the pkg
	metadata files, e.g. +COMMENT, +DESCR, etc., it is of no great
	loss that the timestamps are not preserved in the created pacakge.
	It is a bother when pkg_create leaves garbage in /var/tmp that may
	not be easily removed.  The preservation of the flags is lost in
	pkg since tarfiles cannot handle the file flags.

	FYI, This bug was actually encountered when running "make package"
	for the gmake port.

Fix: Apply the following patch to usr.sbin/pkg_install/lib/file.c.  Note,
	'-r' was replaced with '-R' per the cp(1) manpage's recommendatons.
	Since no recurssive copies were actually found in the code, it may
	be possible to remove '-R' altogether.
How-To-Repeat: 
	# sh
	# cd /tmp
	# for i in DESCR COMMENT PLIST FOO; do echo FOO > $i; done
	# chflags schg /etc/mtree/BSD.local.dist
	# pkg_create -c COMMENT -d DESCR -f PLIST -p /tmp \
		-m /etc/mtree/BSD.local.dist PKG.tgz
