Thank you for the detailed report @bitplane ! This will be straight forward to prevent. A new release is coming in the next few days (will be here) and I'll post a release link in this issue.

If you're looking for a stress test case, the same repo has 200GB Ubuntu repos for x86_64 and aarch64, with as many packages as I could manage to install (well, all the ones that contain binaries that someone might type into a command line).

Source repo is here, if it's the sort of thing you'd find useful :)

This is very cool! Thank you @bitplane

Try the x.1.42.2 version from here. It's a temporary release, but it might do a better job with your image (it's a pretty big image :-))
