Re: a tricky question

[Byron Rakitzis <byron>]

I just thought of a hole: importing functions from the environment.
e.g.,

foo:
	#!/bin/rc --
	echo hi

can be foiled with

; fn echo {/bin/sh}
; foo

or even

	#!/bin/rc --
	exec mount /pcfs

can be foiled with

; fn exec {/bin/sh}
; foo

Then again, Duff mentions "-p" in one of the rc papers, so this one
does not get any credit.

Might it be worth adding "-p" to rc, or would it encourage a false
sense of security? I guess that's what I am driving at.
