Then why are all of the IO-bound low level pieces of Linux userland written in C?

Take just one example: udevd. I have a Fil-C version. There is zero observable difference in performance.

udevd might actually be a good use for Fil-C. Good point.

My fear is that the performance difference might add up once use it on more and more part. I imagine it uses a lot more memory. Plus once Fil-C gets adopted in the mainstream it might lower the need for devs to actually fix the code and they might start just relying on Fil-C.

To be fair, systemd itself is corporate shite to begin with and I wouldn't mind seeing it being replaced with something written in a language with memory safety.

If that argument is valid, then why hasn't it stopped adoption of slow languages?

Like, Python is waaay slower than Fil-C. And so much of Linux userland is written in shell, which is slower still.

Well, the program would still halt upon memory flaw, so there would still be a need to fix it
