Sanity and /var/tmp

[wolfie at cotse.net]

This may be an incredibly stupid. Nevertheless I'm gonna ask...

(1) Is it safe and sane in a RELENG_5_1 system to create and use /var/
tmp via a script in /etc/rc.local:

	[no entry in FSTAB]
	mdconfig -a -t swap -s ... -u 10
	newfs -O2 /dev/md10
	mount /md10 /var/tmp
	chmod 1777 /tmp

(2) Am I sane?
