[arch-projects] [devtools] [PATCH] [RFC] builduser secondary group

I have my SRCDEST folder owned by root:makepkg, where makepkg is a group build users are given. This causes issues with the bind mount when using makechrootpkg. I am using this patch to resolve that problem. Is there be any interest me to expand this out so a `makepkggrp` can be set as an optional argument? Cheers, Ixil
