;;; a shell instead of automatically launching Steam by setting the
;;; environment variable DEBUG=1.  If the sandbox is started this way then
;;; Steam should subsequently be launched via fhs-internal-script.

;;; The sandbox shell aids in debugging missing container elements.  For
;;; example a missing symlink may be created manually before launching Steam
;;; to verify that the fix works before filing a bug report.
