@pid_eins how exactly is a successful boot defined though?

Boots to init?
Boot and all services are started successfully? Some services?

What happens if the system boots successfully, runs for ~60 seconds, and then the kernel panics when the first cron job/timer runs?

@JustinAzoff @pid_eins see the link at the start of the thread, flexible strategies available

@JustinAzoff depends on the usecase. Different systems/OSes want different stuff there. Some might just check if system manages to reach some point in the boot process, others might want to also require network pings to work, other stuff might instead just want to check that some services stay up for some minimum amount of time and so on. systemd gives you the basic infra for this and some super basic tests in this sense, but individual OS images might want to fill in more tests/conditions.

@JustinAzoff I assume anything to make boot more complex also opens up new threats.
