Subject: [9front] [PATCH] vt: rfork environment varibles
Reply-To: 9front@9front.org
Precedence: bulk

Hi,

The patch below fixes the issue of vt(1) leaving behind some
environment variables defined (e.g. $TERM, $COLS, $LINES) after
it exits.

Incidentally, is there a better way to check if a program is
running inside vt(1) besides checking if $TERM is defined?

fhs
