The repo-add source code is "just" a 600 line shell script, but a lot of time is spent parsing arguments etc. This means that it shouldn't be too much work to re-write this in V, with the goal of completely removing any os.execute calls.

Advantages

Cleaner than just running a shell script
Ability to run inside non-Arch container
More granular control over when to lock -> better performance

Tasks

Retrieve .PKGINFO & files list from package archive
Export serialized .PKGINFO & files into desc & files
Check if package is already present
Check if newer package is already present
Calculate md5, sha256 & filesize of new packages

Another big advantage of this would be the ability to run this program without having to rely on an archlinux Docker image. This would make the images much more reliable and a lot smaller.

Having this completely inside the binary will require us to link libarchive, as we need the bsdtar functionality.

We might be able to make our repo-add implementation more efficient by not always deleting the unpackages directories after adding a package to the repository. This would take up a bit more space, but it's just text, so it's not much of an issue.
