The regular invocation of bash is a non-login shell, and thus won't
execute /etc/profile.

Try changing the #! line to "#!/usr/bin/bash -l".  Be aware that you will
not be able to use a relative path either to invoke the script or inside
the script after that, as /etc/profile does a 'cd "$HOME"'.

Alternatively, you can add the following to the top of the script:

if ! shopt -q login_shell; then
  exec -l /bin/bash --login "$PWD/$0" "$PWD" "$@"
fi
cd "$1"
shift

The above should work even with relative paths, but I haven't tested it
extensively.
