Description
systemd-tmpfiles uses the
- configuration files in
- /etc/tmpfiles.d/ to describe the
+ configuration files from the above directories to describe the
creation, cleaning and removal of volatile and
temporary files and directories which usually reside
- in directories such as /var/run
- or /tmp. Each configuration file
- is named in the style of
- /etc/tmpfiles.d/<program>.conf.
+ in directories such as /run
+ or /tmp.
Configuration Format
+ Each configuration file is named in the style of
+ <program>.conf. Files in
+ /etc/ override files with the
+ same name in /usr/lib/. Files in
+ /run override files with the same
+ name in /etc/ and
+ /usr/lib/. Packages should
+ install their configuration files in
+ /usr/lib/, files in
+ /etc/ are reserved for the local
+ administrator, who may choose to override the
+ configurations installed from packages. The list of
+ configuration files are sorted by their filename in
+ alphabetical order, regardless in which of the
+ directories they reside, to guarantee that a
+ configuration file takes precedence over another
+ configuration file with an alphabetically later
+ name.
