Don't kid yourself: binary logs will need compression just as well.
the journal supports inline compression,in ONE format, LZMA, the sane, logical choice.
Isn't it true that with any compression format, any mistake anywhere will invalidate the decoding of all subsequent data, making it totally unreadable?
The only way to avoid that is through redundancy, thus removing the benefits of compression in the first place.
Besides which, the whole notion of tamper proof logs is silly from the start - there is just no such thing. If I achieve root on a system, I have access to every single key used to cryptographically sign anything (no, there can't be passwords for autonomous daemons, at best the password has to be typed in on boot, but after that the key will be available in RAM for root to read).
And with the keys, I can generate any log you care to examine, and you won't be able to tell the difference.
Sure, you can get around it, by limiting what root can do, or logging to another system, or to hardware unchangeable output such as a printer, but then you can do that with any logging system.
Besides besides which, a new kind of logging system is hardly a valid argument in favour of ripping out the entire core infrastructure of the system.
Most arguments in favour of systemd talk about moving forward, but I have yet to see anyone say why it is considered forward. I don't see that we get anything we didn't already have. Fedora lacked infrastructure that they get with systemd, but we already had all of that. And if someone thinks this logging system is neat, take it out and build a replacement for syslog
I see systemd as a massive amount of work, that will net us exactly zero benefit in the end. It won't boot faster, it won't enable us to do anything new that we couldn't already do before, and we will have amassed a ton of bugs in the process.
I still propose that we drop systemd completely
