I'm sorry for an unrelated question, but why is it really necessary to make a
new container for each pkg? It seems lots of unnecessary copies (I think
rsync(1) call in makechrootpkg doesn't do hardlinks)...
I understand the issue about getting unlisted deps in packages, but in my
experience this problem is minor. So just boot a build container and ssh in
there as a non-root user (in fact, you don't even need root inside the
container). And keep it clean. At least this has worked for me for years.
Also, with newer -ARCH kernels, you can do non-privileged containers, so
makechrootpkg should run as a ordinary user to begin with...
