[bug#61982] [PATCH 2/2] home: services: xdg-base-directories: Deprecate XDG_LOG_HOME. |
|
Date: |
Sun, 5 Mar 2023 15:19:14 +0000 |
XDG_LOG_HOME is non-standard and log files should go to XDG_STATE_HOME
according to the XDG Base Directory Specification.
Fixes <https://issues.guix.gnu.org/61809>.
* gnu/home/services/desktop.scm (home-dbus-shepherd-services): Log to
XDG_STATE_HOME.
* gnu/home/services/mcron.scm (home-mcron-shepherd-services): Ditto.
* gnu/home/services/pm.scm (home-batsignal-shepherd-services): Ditto.
* gnu/home/services/shepherd.scm (launch-shepherd-gexp): Ditto.
* gnu/home/services/xdg.scm
(home-xdg-base-directories-configuration)[log-home]: Deprecate and unset
default value.
(home-xdg-base-directories-environment-variables-service)
(ensure-xdg-base-dirs-on-activation): Handle field deprecation.
(home-xdg-base-directories-service-type): Update description.
