30 What Canek and Rich already said is good, but I'll just add this: it's not like
31 you can't run a classic syslog implementation alongside the systemd journal.
32 On my systems, by *default*, syslog-ng kept working as usual, getting the logs
33 from the systemd journal. If you want to go further, you can even configure
34 the journal to not store logs permanently, so that you *only* end up with
35 plain-text logs on your system (Duncan on gentoo-amd64 went this way).
36
37 So no, the format that the systemd journal uses is most decidedly *not* a reason
38 against using systemd.
39
40 Personally, I'm probably going to uninstall syslog-ng, because journalctl is
41 *such* a nice way to read logs, so why run something whose output I'll never
42 read again? I recommend reading
43 http://0pointer.net/blog/projects/journalctl.html for examples of the kind of
44 stuff you can do that would be cumbersome, if not *impossible* with regular
45 syslog.
