Re: Cloud Atomic ISO, missing items for baremetal usage
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.

Maybe lsblk, by virtue of libblkid, gets some state update for free, I
don't know. 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.
