That newfangled Journal thing

As for what will be broken. I expect a lot will be broken in the strongly suggested patch to change all of the user space programs to ad uuids into their log messages. The change is to huge and too vast to prevent tupos from slipping through.

Furthermore their is no indication that such a change will benefit anyone in practice.

In their faq they have already deprecated syslog(3).

Better log messages are mostly a matter of getting the human factors right. I do not see journald doing anything but adding yet another ABI to user space that will have to reasonably be supported forever but that adds nothing of substance, and confuses the issue about how to do a good job of logging messages.

The design appears to have a very high cost to even experiment with, and he design is clearly not thought all of the way through at this point. I see any depolyment of journald as described as achieving exactly the opposite of what it hopes to achieve. That is I see deploying journald as creating an even bigger mess in the logging space then what already exists.
