Most workarounds to the issue stipulates adding a docker workaround:
--ulimit nofile=1024:524288
This only works in some instances, and this might be obvious to others..
But if running for instance makepkg[1] inside a docker container the
issue will remain. Unless makepkg specifically was executed with ulimit.
For instance (in the docker image):
ulimit -n 1024 && makepkg -s
Otherwise the ulimit on docker itself has little to no effect.
