Default smartd.conf behavior

Hi,

My smartd.conf only has the line:

DEVICESCAN

With no directives explicitly specified. The docs say this means the
'-a' directive will be passed to all disks detected by DEVICESCAN.

What are the default settings for offline testing? Will smartd perform
regular offline (immediate?) tests if "-o on" isn't specified? I'm
actually a bit confused as to what checks smartd performs if you don't
specify anything.

What are the default settings for attribute autosave? Will attribute
values be saved to NV memory if "-S on" isn't specified? I see
attribute values change even though I haven't explicitly specified
"-S" (but maybe that's because that flag just happens to be set on the
disk?)

Thanks,

Preet
