I'm trying to test only the job id:
com.canonical.certification::power-management/suspend_30_cycles_with_reboots

To be sure to save the respawn command in the session share, I've only added flags: noreturn to this job.

But executing the following makes checkbox-cli to crash:

$ checkbox-cli run .*with_reboots
[...]

Waiting for the system to shut down or reboot...
