>Description:
	While working on setting up a restricted shell on one of my home
	machines, I found that the bash port doesn't have any framework
	to create PREFIX/bin/rbash.  Since one cannot set a users' shell
	in passwd to "/usr/local/bin/bash -r", this does pose a problem.

	Solution is obvious: just ln -s or ln bash to rbash.  But it
	would be great if the port could do this, as well as update
	/etc/shells to reflect support for rbash.
>How-To-Repeat:
	n/a
>Fix:
	I'd propose adding something called WITH_RBASH which would make a
	hardlink for rbash, and of course track it in the package list
	so it gets removed on pkg_delete.  Same goes for updating /etc/shells
	when the port with rbash support is added and removed.

	Either that or one could just make the port do this by default and
	go with WITHOUT_RBASH, but I think *most* people won't use this
	feature, so I'm voting for WITH_RBASH.  :-)

	Thanks!
