This is a proof-of-concept showing how we can use
kexec
to support reinstalling assuming we have access to the rootfs image (this is strongly related to or exactly the same as coreos/fedora-coreos-tracker#399 depending on which flavour of "reset" we're talking about).Demo:
(I've cut out a lot of stuff from the logs there to concentrate on the interesting bits; see this attachment for the full output if you're curious.)
It also supports specifying the target Ignition config, image URL, using a local live initramfs and live rootfs, etc...
FCOS is also supported though for there seems to be a bug in the kexec code there.
