OK at this moment I'm thinking hdparm and smartmontools just need to go on the ISO, along with iotop. While both hdparm and smartmontools appear to work OK in a container with --privileges=true, any hardware changes are not reflected in that container in a way these two programs can see.

Clearly that's not the case for hdparm and smartctl, and therefore I have to restart the container or start a new one for the change to be visible to these tools. If I replace or add drives, will I need to restart the container running smartd? If yes, that'd kinda be a regression. Maybe I'm doing something wrong, but at the moment I'm not groking the advantage of running these tools in a container.
