You can specify these in newsyslog.conf, see newsyslog(8) :

     path_to_pid_file
             This optional field specifies the file name to read to find the
             daemon process id, or to find a process group id if the U flag
             was specified.  If this field is present, a signal_number is sent
             the process id contained in this file.  If this field is not
             present, then a SIGHUP signal will be sent to syslogd(8), unless
             the N flag has been specified.  This field must start with "/" in
             order to be recognized properly.

     signal_number
             This optional field specifies the signal number that will be sent
             to the daemon process (or to all processes in a process group, if
             the U flag was specified).  If this field is not present, then a
             SIGHUP signal will be sent.
