@majortom Hi, I do not have a script, I did it almost manually. My initial idea was trying to use the btrfs on Debian Image 69, but then I realized that the Debian image is fixed to a snapshot version of debian which is pretty old. So I tried to use my custom kernel on Arch Linux which already published the rootfs on https://riscv.mirror.pkgbuild.com/.
By the way, there are some more details before the Arch’s rootfs can boot for the first time on VF2. I will document it later on my blog, and will post the link here.
