	Unison Installation Notes

	To work, unison requires an environment variable UNISON to point at
	a writable directory. Unison keeps information there between syncs to
	speed up the process.

	When a user runs the unison client, it will try to invoke ssh to
	connect to the this server. Giving the local ssh a UNISON environment
	variable without compromising ssh turned out to be non-trivial.
	The solution is to modify the default path found in /etc/login.conf.
	The path is seeded with "UNISON=/mnt" and this updated by the
	/etc/rc.d/unison file.

	Todo:
	* 	Arguably, a full client install could be done too to
	allow FreeNAS to FreeNAS syncing.
