What is the difference between tmp and var tmp?
4 Answers. /tmp is meant as fast (possibly small) storage with a short lifetime. Many systems clean /tmp very fast – on some systems it is even mounted as RAM-disk. /var/tmp is normally located on a physical disk, is larger and can hold temporary files for a longer time.
What is var tmp for?
Purpose. The /var/tmp directory is made available for programs that require temporary files or directories that are preserved between system reboots. Therefore, data stored in /var/tmp is more persistent than data in /tmp . Files and directories located in /var/tmp must not be deleted when the system is booted.

What does systemd-tmpfiles do in / tmp / and / var /?

When to clean up files in / var / tmp?
By default files in /tmp/ are cleaned up after 10 days, and those in /var/tmp after 30 days.
