Hi,
i wonder if it's possible to

depthchargectl build --board=veyron_speedy --output veyron.img

from another machine.

It should work, but you would need to specify kernel, initramfs, fdtdir/dtbs, root, and kernel cmdline args to get something that actually boots. I remember using --board kevin from an amd64 laptop to pack e.g. Arch Linux ARM, Debian Installer.

OTOH, I never tested this on anything except kevin. I can only hope my best guesses work on other boards.

ok, i suppose it's easier to bootstrap the img from a qemu environment.

I ended up adding a global --root argument that can be pointed to chroot mountpoints. So depthchargectl build --board speedy-libreboot --root /mnt --output veyron.img from another computer would build an image for veyron and that installation. Even depthchargectl write should work and write to the disk the moutpoint is for.
