velvet os - simple script framework to build ubuntu 22.04 lts jammy (in older versions also 20.04 lts focal) and debian 12 bookworm (in older versions also 11 bullseye) bootable usb / sd card images for some arm and intel devices - lots of prebuilt images as well
Why do you think that https://github.com/quarkscript/linux-armv7-xe303c12-only is a good alternative to imagebuilder
