Each entity associated with a non-zero PID (this includes most kernel threads) has a corresponding toplevel procfs directory named by its PID (e.g. when using [[systemd]] as init and mounting procfs at <tt>/proc</tt>, systemd's primary process is described by <tt>/proc/1</tt> (the process only appears in procfs mounts within the same PID namespace).
