Configuration for creation, deletion and cleaning of volatile and temporary files.

tmpfiles.d 디렉토리의 설정 파일들은 tmpfs 및 temporary directory 의 임시 파일들을 관리한다.
<pre>
/etc/tmpfiles.d/*.conf
/run/tmpfiles.d/*.conf
/usr/lib/tmpfiles.d/*.conf
</pre>

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.

Volatile and temporary files and directories are those located in /run (and its alias /var/run), /tmp, /var/tmp, the API file systems such as /sys or /proc, as well as some other directories below /var.

System daemons frequently require private runtime directories below /run to place communication sockets and similar in. For these, consider declaring them in their unit files using RuntimeDirectory if this is feasible.
