Miao, I am actually concerned about backward compatibility with existing code *without* the need to upgrade any of that code. As you know, deployed software tends to stick.
If we use just LF, existing, deployed technology (e.g. syslog-ng with stunnel) would be able to understand a message sent from a "new style" syslogd. Having the octet count in front of the message removes that ability, as the old syslogd will no longer see the <pri> at the start of the message. I agree that it is trivial to modify code to take care for the octet counter. But this is not my concern. My concern is that I would like to achive as good as possible compatibility with existing deployed (aka "unmodified") technology. I should have been more specific on that. Sorry for the omission... I am also unaware of any implementation that mandates CR LF over just LF. Could you let me know which ones are these?
