*
* This is the base directory relative to which user-specific
* non-essential runtime files and other file objects (such as
* sockets, named pipes, ...) should be stored. The directory @b must
* be owned by the user, and he @b must be the only one having read
* and write access to it. Its Unix access mode @b must be 0700.
*
* The lifetime of this directory @b must be bound to the user being
* logged in. It @b must be created when the user first logs in and if
* the user fully logs out the directory @b must be removed. If the
* user logs in more than once he should get pointed to the same
* directory, and it is mandatory that the directory continues to
* exist from his first login to his last logout on the system, and
* not removed in between. Files in the directory @b must not survive
* reboot or a full logout/login cycle.
*
* The directory @b must be on a local file system and not shared with
* any other system. The directory @b must by fully-featured by the
* standards of the operating system. More specifically, on Unix-like
* operating systems AF_UNIX sockets, symbolic links, hard links,
* proper permissions, file locking, sparse files, memory mapping,
* file change notifications, a reliable hard link count must be
* supported, and no restrictions on the file name character set
* should be imposed. Files in this directory @b may be subjected to
* periodic clean-up. To ensure that your files are not removed, they
* should have their access time timestamp modified at least once
* every 6 hours of monotonic time or the 'sticky' bit should be set
* on the file.
*
* If @c NULL applications should fall back to a replacement directory
* with similar capabilities and print a warning message. Applications
* should use this directory for communication and synchronization
* purposes and should not place larger files in it, since it might
* reside in runtime memory and cannot necessarily be swapped out to
* disk.
*
* @note this directory is similar to @c /run and is often created in
* tmpfs (memory-only/RAM filesystem). It is created, managed and
* cleaned automatically by systemd.
