I tried this and it didn't appear to work at first, but I believe
it is because of this.
steve[~]$ grep steve /etc/passwd
steve:*:1000:1000:Steve Price:/home/steve:/bin/bash
steve[~]$ echo $ENV
/home/steve/.bashrc
steve[~]$ cat /home/steve/.bashrc
steve[~]$ cat /home/steve/.profile
export ENV=${HOME}/env-stuff
echo ~/.profile
steve[~]$ cat /home/steve/env-stuff
echo "Yep I'm here!"
steve[~]$ sh
\u[\w]\$ exit
steve[~]$
But after I change my login shell to /bin/sh or do a
export ENV=${HOME}/env-stuff. It works as suspected. It appears
to be a problem in that ~/.bash_profile is getting sourced and
ENV is picked up from there. The reason that this would matter
is that ~/.profile (or ~/.bash_profile for bash's case) is only
getting sourced when it is started as a login shell. So just
typing 'sh' will not source ~/.profile, but will source $ENV (which
was set by your login shell) if your euid == uid && egid == gid.
Could this be the case with you as well?
