kata-irc-bot<david532> If this is better for kata-dev , let me know.23:17
kata-irc-bot<david532> Inside the thread is the script I've compiled to bootstrap my debug image, but I'm unsure if something I've done is wrong.23:24
kata-irc-bot<eric.ernst> @david532 you have the services for debug shell in and running in the rootfs23:29
kata-irc-bot<david532> The debug proces was within /rootfs/usr/lib/systemd/system/kata-debug along with kata containers and agent services.23:29
kata-irc-bot<eric.ernst> And can you verify that that particular toml is being used? Ie, swap vmlinuz to foo and make sure it fails?23:29
kata-irc-bot<david532> Kata runtime list all showed that it was running on the initd and debug image.23:30
kata-irc-bot<david532> Let me see if I can grab another Packet instance.23:31
kata-irc-bot<david532> Did you want an ls on the root showing kata-containers, kata-agent, and kata-debug along with `kata-runtime list --kata-all` with a running container?23:32
kata-irc-bot<david532> Would that help?23:32
kata-irc-bot<david532> I will record my session with `asciinema` whihc might be of assistance in an environment where I might not have the server in an hour or two.23:36
