As quoted, it makes no sense anyway. The mere existence of a file cannot
be used as check on whether or not a process is running. Whether or not
the directory is cleaned on boot, one can still have lpd exit/crash in a
way that doesn't remove the file. Therefore, anything checking the file
must also check that referenced process id a) is still running, and b)
is actually lpd. Anything less than that is bug is the program doing the
check.

Create a symlink from from /var/spool/lpd/lpd.lock to /var/run/lpd.pid.

Not really.
