#29 make POSIX shell compliant

[Tom Metro]

This post:

comments that FireHOL is not usable on the OpwnWRT
Linux distribution, because FireHOL depends on bash,
and the resource constrained environment that OpwnWRT
runs in can't easily support bash.

It suggests porting FireHOL to use ash, a minimalist
POSIX compliant shell.

In addition, this portion of the "Debian Weekly News"
(August 30th, 2005) mentions POSIX compliance and may
have some useful resources:

"Posix-compliant Scripts. Brian Carlson [13]suggested
that all maintainers test their packages with [14]posh
as standard shell. Steve Langasek asserted that the
practical impact would be zero since the POSIX
extensions mentioned are supported by the other shells,
including [15]busybox. Marco d'Itri [16]added that posh
does not even provide a size benefit."

I don't have an immediate need for running FireHOL
under OpwnWRT, but hope to do so in the future, and so
I'd be willing to assist in a port.
