 To keep the system functional, the needed log directory structure is automatically created at startup, ensuring that applications expecting these directories will not fail and critical system services can still operate normally.

   * **size=512M** or **size=50M** – Limits the maximum amount of RAM each directory can use to prevent memory exhaustion.

+The amount of RAM for /var/log can be increased as needed.

+  * Alternatively, temporarily disable the tmpfs mounts by commenting out the relevant lines in /etc/fstab and rebooting.
