I mainly want that the packages ./build.sh downloads, are retained in a
permanent cache. I am fine with rebuilding all the squashfs files, and
not reusing the existing iso.

removes the packages from the pacman cache directory.

Alternatively, can it use the chroot environment's pacman cache?

Thanks, this also answered another question in my mind, that where does
the arch user come from.

I am using the releng method, as specified on the wiki. Maybe the wiki
needs a bit of more detailed info.

Thanks for all the explanation.
