zsync support #16
Description
I sometimes run a quick kvm on an Arch iso to test upstream changes in a clean environment. Downloading only the differences from a previous iso would be faster and lighten a bit the load on the mirrors.
The reasons I use the iso are that the setup around installing or making a container takes more time than the testing (it's not pacstrap but the steps before / after) and that I am a happy Debian user, due to lack of time to invest in a rolling distro.
I was pointed to PR #4 from 2021 Create zsync control file but it was closed recently.
