OT, but I wonder why Poettering chose Kay Sievers to work on systemd in the first place.

Remind me, why are such critical system components as systemd are still being written in a memory unsafe language?

Because all other languages have higher overhead or are less stable.

Both are Germans, and work at RH.

Frankly the more i look at things, the more i find a small group of people at the RH German office to be the source of recent turmoil.

Yeah, we really should rewrite the kernel.

Err, that is not an excuse. That just leads to the question of why there is a second kernel metastasizing in userspace.

Earlier quoted context omitted.

I believe it was a joke about how Lennart Poettering usually responds to bug reports.

You are correct. See, for example, his recent response to the issue where systemd starts processes belonging to users whose usernames begin with a digit with root privileges: https://github.com/systemd/systemd/issues/6237#issuecomment-... My deepest apologies to HN for the overly-dry sense of humor.

Was that the only reason?
