start-stop-daemon already does this:



START-STOP-DAEMON(8)     Debian GNU/Linux    START-STOP-DAEMON(8)


--make-pidfile
              Used  when  starting a program that does not create
              its own pid file. This option will make start-stop-
              daemon  create  the  file referenced with --pidfile
              and place the pid into it just before executing the
              process. Note, it will not be removed when stopping
              the program.  NOTE: This feature may  not  work  in
              all cases. Most notably when the program being exe­
              cuted forks from it's main process. Because of this
              it  is  usually  only useful when combined with the
              --background option.
