bgm's trick for enabling system log
1. In the shell, do: echo "*.* /var/log/syslog" > /etc/syslog.conf
2. Add the following tags to /System/Library/LaunchDaemons/com.apple.syslogd.plist after the tag <string>/usr/sbin/syslogd</string>
<string>-bsd_out</string> <string>1</string>
This will tell the Daemon Launcher to call /usr/sbin/syslogd -bsd_out 1, and we have configured it to write all messages to /var/log/syslog
3. "reboot & enjoy your kernel and other messages" (bgm)
Note
The syslog will grow very big quite quickly, but the folder /var/log/syslog is on the data partition (music, etc).
If you keep your device full of music, be careful you don't fill the partition. Unix systems tend to break when they
cant write to the syslog. Keep an eye on it or employ some log rotation.
To disable: In a shell, do:
rm /var/log/syslog; mknod /var/log/syslog c 3 2
This will turn /var/log/syslog into a /dev/null
To reenable: In a shell, do:
rm /var/log/syslog; touch /var/log/syslog
This will remove the /dev/null and make a blank regular file
