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.
