I tried multiple things to repro this crash without success: - Used the config on my existing qemu setup (boot fine) - Add most of the command-line (boot fine) - Try to run the script on a dedicated machine and it seems it is really tailored for your setup. I had errors with usernames and cpio crashing.
Any additional information you could share? (RIP -> function name, callstack etc..?)
