all configuration directories as specified in

<para>It is possible to combine

<option>--create</option>, <option>--clean</option>,

and <option>--remove</option> in one invocation. For
|
|
example, during boot the following command line is

|
executed to ensure that all temporary and volatile
|
|
directories are removed and created according to the
|

configuration file:</para>

<title>Unprivileged --cleanup operation</title>
|
|
|
|
<para><command>systemd-tmpfiles</command> tries to
|
|
avoid changing the access and modification times on
|
|
the directories it accesses, which requires
|
|
<constant>CAP_ADMIN</constant> privileges. When
|
|
running as non-root, directories which are checked for
|
|
files to clean up will have their access time bumped,
|
|
which might prevent their cleanup.
