Ctrl-c now goes through. Thanks! Exiting the linux instance says "reboot: Restarting system\nUnauthorized access" and then hangs eating 100% cpu, but maybe I can fix that with kernel configuration changes. (I'm still doing a variant of https://landley.net/aboriginal/control-images so the virtual system needs to be able to indicate when it's done. But https://landley.net/aboriginal/about.html is getting replaced with https://github.com/landley/mkroot so there's some plumbing to do before that's blocking anything...) Thanks again, Rob
