makepkg needs a lot of system resources. I would like it to be able to nice itself.
Patch is attached and works for me.

Reason for closing:  Won't implement
Additional comments about closing:  an alias is sufficient and more flexible

What is the advantage of doing it this way compared to:

alias makepkg="nice -n5 makepkg"

With the alias, you can at least run without nice using "\makepkg" and not requiring the editing of a configuration file.

I use makepkg in a number of scripts that do not get my aliases.

On the other side I would prefer to call "NICE=0 makepkg" to have it not nice itself. (Attached a new patch to support that.)

alias makepkgnice='nice -n5 makepkg'

It does seem we are overcomplicating something very simple here. The nice tool is built for and can wrap around any command out there.

I've found better solution. Simply added following line to makepkg.conf:
renice -n 9 -p $$
can you please add it (commented) to distribution of makepkg.conf so other users will not have to reinvent it?

That works? Sure, the file is sourced from makepkg... Really great! Thanks a lot!

This works much better as makepkg.conf is not sourced only from makepkg:

[ "$0" = '/usr/bin/makepkg' ] && renice -n 9 -p $$


I am even sourcing it from profile.d to have system-wide cflags which turned out to be a problem:

. /etc/makepkg.conf
export CARCH CHOST CFLAGS CXXFLAGS LDFLAGS MAKEFLAGS;
