On most distributions, /var/run is a symbolic link to /run so using
/var/run or /run lead to the same result. Nevertheless systemd started
to warn about using /var/run in a service file, logging entries such as:
/usr/lib/systemd/system/restorecond.service:8: PIDFile= references
path below legacy directory /var/run/, updating
/var/run/restorecond.pid → /run/restorecond.pid; please update the
unit file accordingly.
Switch to /run in order to follow this advice.
