Question

If I had used htop(1) F7 to increase the priority of the selected command (a parent) then the increase would take effect:

• for the next port in the queue
• but not for the already running build of gpu-firmware-kmod

– true?

(Apologies for the basic question. I have used FreeBSD for years, but never really used nice or renice.)

Children inherit the current priority of a process when they're created. That means, if you renice the parent and start a child, it will have the modified priority. …

It would really be nice if info from https://forums.freebsd.org/posts/563555
either comment 7 or 11 were included so all people could enjoy interactive responsiveness.
Could poudriere auto magically use those nice and idprio settings?
