Also he has no regards for breaking userspace to the point of needing to get scolded by Linus. But some ideas are good and there is a lot of pioneering work that moves the needle. The trajectories of PulseAudio and systemd are similar, it just needs cleaning up. PulseAudio got fixed up by PipeWire, whereas systemd is at the point of lifecycle yet to reach that stage.

Afaik one of the main problem with the software of his is that it tends to sacrifice ergonomics in the 99% common cases for some obscure theoretical observation.

This is of course about tradeoffs and about the complexities of the problems you're solving, but his software is full of choices that only make sense if you priorize elegant code over elegant software only to then grow into something that is neither.

Lennart worked at Red Hat when he was developing systemd. Red Hat's largest customers often have wacky, weird requirements that you would have never thought of unless you were in that specific customer's situation.

Good point.

It doesn't mean the requirements and solutions aren't wacky, weird, or inscrutable though.

Yeah sure, I didn't intend to paint it as if these problems were easy to solve. They are not.

Didn't take it that way, I was trying not to minimize the opposite point of view. systemd is a riddle wrapped up in a big ball of wtf.

There's a podcast [1], which features him as a guest to talk about Linux in general. The main impressions I got from it: he is very confused about what UNIX is and he apparently despises UNIX.

I think he's well suited for his new employer (Microsoft).
