Re: passing environment variables through to screen

Thanks for the response.  In case this hits anyone else, the
problem is this is a Linux security measure due to screen being
setgid.  This seems Linux-specifc in the system and specific to TMPDIR
and certain other environments variables.  See below.  It's
mentioned here:

         https://bugzilla.redhat.com/show_bug.cgi?id=129682#c1

Although this is not documented in man ld.so(8) as suggest in
one of the postings.

The best work around I can see is to have TMPDIR set in
/etc/screenrc.

FreeBSD 8.2, OS/X 10.7.4:
    TMPDIR=/var/barney FRED=fred screen 
    echo $TMPDIR
    /var/barney
    echo $FRED
    fred

CentOS 5.2, Ubuntu 12.0
    TMPDIR=/var/barney FRED=fred screen 
    echo $TMPDIR
    bash: TMPDIR: unbound variable
    echo $FRED
    fred
