Description
- systemd-tmpfiles uses the
- configuration files in
- /etc/tmpfiles.d/ to describe the
- creation, cleaning and removal of volatile and
- temporary files and directories which usually reside
- in directories such as /run
- or /tmp. Each configuration file
- is named in the style of
- /etc/tmpfiles.d/<program>.conf.
+ systemd-tmpfiles uses the

+ temporary files and directories which usually reside

+ or /tmp.

+ Configuration Format
+
+ Each configuration file shall be named in the
+ style of <program>.conf.
+ Files in /etc/ override files
+ with the same name in /usr/lib/
+ and /run/. Files in
+ /run/ override files with the same
+ name in /usr/lib/. Packages
+ should install their configuration files in
+ /usr/lib/. Files in
+ /etc/ are reserved for the local
+ administrator, who may use this logic to override the
+ configuration files installed by vendor packages. All
+ configuration files are sorted by their filename in
+ alphabetical order, regardless in which of the
+ directories they reside, to guarantee that a specific
+ configuration file takes precedence over another file
+ with an alphabetically later name
+
+ If the administrator wants to disable a
+ configuration file supplied by the vendor the
+ recommended way is to place a symlink to
+ /dev/null in
+ /etc/tmpfiles.d/ bearing the
+ same file name.
