From: Brian Cully <bjc <at> spork.org> To: 62726 <at> debbugs.gnu.org Cc: Brian Cully <bjc <at> spork.org> Subject: [bug#62726] [PATCH] services: Activate `setuid-program-service-type' in shepherd. Date: Sat, 8 Apr 2023 11:16:35 -0400
Activate using a one-shot Shepherd service on boot, rather than attaching to
`activation-service-type' to populate `/run/setuid-programs'.
In order to prevent a dependency cycle between (gnu services) and (gnu
services shepherd), introduce a new module (gnu services setuid) and deprecate
the import of `setuid-program-service-type' from (gnu services).
* gnu/local.mk (GNU_SYSTEM_MODULES): add setuid.scm.
* gnu/services.scm (setuid-program-service-type): deprecate.
* gnu/services/setuid.scm: new module.
* gnu/services/dbus.scm (gnu): import (gnu services setuid).
* gnu/services/desktop.scm (gnu): import (gnu services setuid).
* gnu/services/docker.scm (gnu): import (gnu services setuid).
* gnu/services/mail.scm (gnu): import (gnu services setuid).
* gnu/services/xorg.scm (gnu): import (gnu services setuid).
* gnu/system.scm (gnu): import (gnu services setuid).
