Message #18 received at 62726 <at> debbugs.gnu.org (full text, mbox):
From: Brian Cully <bjc <at> spork.org> To: 62726 <at> debbugs.gnu.org Cc: Brian Cully <bjc <at> spork.org> Subject: [PATCH v2] services: Activate `setuid-program-service-type' in shepherd. Date: Wed, 7 Jun 2023 08:59:17 -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).
Add the new SETUID-PROGRAMS Shepherd service to the extant Shepherd services
which need it, as well as USER-PROCESSES as a catch for things started later.
* gnu/local.mk (GNU_SYSTEM_MODULES): add setuid.scm.
* gnu/services.scm (setuid-program-service-type): removed.
* gnu/services/setuid.scm: new module.
* gnu/services/dbus.scm (gnu): import (gnu services setuid).
(dbus-shepherd-service): require SETUID-PROGRAMS.
* 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).
(<opensmtpd-configuration>): require SETUID-PROGRAMS.
* gnu/services/xorg.scm (gnu): import (gnu services setuid).
* gnu/system.scm (gnu): import (gnu services setuid).
* gnu/system/pam.scm (gnu): import (gnu services setuid).
(pam-root-service): require SETUID-PROGRAMS by default.
