Then inform people whose software is printing that message – it's not
systemd's output. You're currently starting dhcpd via Debian's
auto-generated "compatibility" .service, which merely starts
/etc/init.d/isc-dhcp-server and lets it do whatever it used to do back in
the dark ages; this apparently includes printing messages with typos and
exiting when it finds a stale pidfile.
