It's essential that stored records survive both a service restart and a host reboot. I should check if `systemctl` is enabled for persistence. We might want to explore the system boot target and see if a reboot command could be executed without issues. It's crucial to ensure everything is durable.**Evaluating contract durability**\n\nI'm working on ensuring that the contract evaluator can handle a reboot test. I need to verify that it’s already enabled and check for any potential application startup errors. It's important that persistent records survive both service and host reboots. The path should be \"/var/lib.\" Also, I should consider if the system might rollback upon reboot. The `systemd` settings seem good, but I need to address potential issues with encoding and HTTP request formatting. Overall, I’m focusing on making the test as thorough as possible.**Assessing service unit details**\n\nI’m looking into a service unit that doesn’t have a `WorkingDirectory` or an app path, but that's fine. The systemd path for the application is `/opt/builder/app.py`, and it must be executable. Potential tests may expect a `PUT /records/<id>` request with a numeric ID for storage. If there's a concurrent `PUT` for the same ID, the last one should be valid. I need to consider if a host reboot might cause the service to start before `/var` is ready, given the systemd mounting order.**Checking system status**\n\nI think I need to use `systemctl show` to look at the UnitFileState. Also, I should verify the record file and check the service logs. Running `systemctl is-active` and `systemctl is-enabled`, along with `systemctl show`, sounds like a good plan.
