tmpfiles.d
- configuration for creation, deletion and cleaning of tmpfiles
+ Configuration for creation, deletion and
+ cleaning of volatile and temporary files
+
+ /usr/lib/tmpfiles.d/*.conf
+ /etc/tmpfiles.d/*.conf
+ /run/tmpfiles.d/*.conf
+
+
Description
- systemd uses /etc/tmpfiles.d/ to describe the creation, cleaning and removal of temporary files and directories
-which usually reside in /var/run or /tmp).
-Each configuration file is named in the style of
-/etc/tmpfiles.d/<program>.conf
-
+ systemd-tmpfiles uses 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 /run
+ or /tmp.
Configuration Format
- The configuration format is one line per path containing
-action, mode, ownership and age fields:
+ Each configuration file is named in the style of
+ <program>.conf.
+ Files in /etc/ overwrite
+ files with the same name in /usr/lib/.
+ Files in /run overwrite 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
+ administration, which possibly decides to overwrite the
+ configurations installed from packages. All files are sorted
+ by filename in alphabetical order, regardless in which of the
+ directories they reside, to ensure that a specific
+ configuration file takes precedence over another file with
+ an alphabetically later name.
+
+ The configuration format is one line per path
+ containing action, mode, ownership and age
+ fields:
+
+ Type Path Mode UID GID Age
+d /run/user 0755 root root 10d

+
+ Type

+ f

+ x
+ Ignore a path
+ during cleaning. Use this type
+ to exclude paths from clean-up
+ as controlled with the Age
+ parameter. Note that lines of
+ this type do not influence the
+ effect of r or R lines. Lines
+ of this type accept
+ shell-style globs in place of
+ of normal path
+ names.

+
+
+ Mode
+
+ The file access mode to use when
+ creating this file or directory. If omitted or
+ when set to - the default is used: 0755 for
+ directories, 0644 for files. For z, Z lines
+ if omitted or when set to - the file access mode will
+ not be modified. This parameter is ignored for x, r, R
+ lines.
+
+
+
+ UID, GID
+
+ The user and group to use for this file
+ or directory. This may either be a numeric
+ user/group ID or a user or group name. If
+ omitted or when set to - the default 0 (root)
+ is used. For z, Z lines when omitted or when set to -
+ the file ownership will not be modified.
+ These parameters are ignored for x, r, R lines.
+
+
+
+ Age
+ The date field, when set, is used to
+ decide what files to delete when cleaning. If
+ a file or directory is older than the current
+ time minus the age field it is deleted. The
+ field format is a series of integers each
+ followed by one of the following
+ postfixes for the respective time units:
+
+
+
+ s
+ min
+ h
