For <function>session_gc</function> to work correctly, the
<link linkend="ini.session.save-path">session.save_path</link> must be set
to the same value as web requests and the script must have access and
permissions for the same files. This may be affected by the user the script
runs as and container / sandbox features such as SystemD's PrivateTmp.
