How to configure syslogd to listen to UDP in El Capitan?
Older Apple Airport base stations have the ability to log via syslog’s UDP transport. By default, however, syslogd on Mac OS X doesn’t set up a UDP listener.
In Yosemite, it was relatively easy to enable the UDP listener by editing /System/Library/LaunchDaemons/com.apple.syslogd.plist, as described in the syslogd(8) man page. Presumably the same would work in El Capitan, except that the sandbox prevents modification of that file.
I’d rather not disable System Integrity Protection just to make this change, and it seems like an oversight that there isn’t a way to configure this which doesn’t involve changing a file in /System. Is there any other mechanism which I’m overlooking?
