rc: allow syslog (service logging) to read options from /etc/syslogd.cfg
Note that is's not ".conf" in order to avoid confusion with the REAL syslogd.
Options are: rotate_size num_of_rotations_to_keep output_filename
All on the first line of the file, separated by spaces. A "-" means to use the
Tomato default for that number.
You have to create that file,
for example: echo "500 10 /mnt/TOSH_120/z.logs/syslog" >/etc/syslogd.cfg
then execute: service logging restart
It won't use the new logfile unless it can write to it in start_syslog.
So the restart command needs to be in a script that is executed after the disk is mounted.
