;;; The steam script provided by this package may optionally be started as
;;; 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.
;;; Steam should subsequently be launched via fhs-internal.
;;; 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.
;;; A container wrapper creates the following store items:
;;; * Main container package [nonguix-container->package] (basically a dummy
;;; package with symlink to wrapper script)
;;; - Wrapper script [make-container-wrapper] (runs "guix environment")
;;; References:
;;; -> manifest.scm [make-container-manifest] (used by wrapper to guarantee
;;; exact store items)
;;; -> container-internal [make-container-internal] {inside container}
;;; (dummy package added to container with symlink to internal-script)
;;; - internal-script [make-internal-script] {inside container}
;;; (script run in-container which performs additional setup before
;;; launching the desired application)
;;; References:
;;; -> Wrapped package {inside container} (in this case Steam).
;;; Note: The extra container-internal package is necessary because there is no
;;; way to add the container package's own store path to its own manifest unless
;;; the manifest is printed inside the build phases. However, the (guix gexp)
;;; module is apparently disallowed inside build phases.
