`-v ~/projects/iso-cache:/var/cache/pacman/pkg` keeps the downloaded packages
(~3 GB) between builds (`mkdir -p ~/projects/iso-cache` once): the container's
own tools and mkarchiso's `pacstrap -c` both use that cache, so only updated
packages are downloaded. Clear it with `sudo rm -rf ~/projects/iso-cache/*`
if it grows too large.
`build-calamares-modules.sh` builds Calamares' `packagechooserq` (the Steamify `build-calamares-modules.sh` builds Calamares' `packagechooserq` (the Steamify
