More magic is required to fake a target system; see:

http://freenas.svn.sourceforge.net/viewvc/freenas?view=revision&revision=8193

(and the corresponding post made by ambrisko@). More magic was
required to deal with $PATH, etc... but you should be able to grok all
you need from that function (it hasn't been modified too much since I
left iX).

This should be `=` in order to be backwards compatible with older
(pre-9.1) copies of /bin/sh
