system.smartctl.smartinfo collects information from the smartctl command.

1. Check if SMART is available and enabled
2. If not enabled, enable it and re-check if it's enabled. Fail in case it can't be enabled
3. Add to ScanResult instance:
   1. Duration of short self test
   2. If ATA Secure Erase is available

Once #3 is solved, we should be ready to overwrite drives.

(Step zero: Receives a request and generates a new job_id for which the overwrite job progress and results will be collected and store)

1. Gather a "before" sample of data from random sector, store it in the results
2. Perform SMART self test if available
3. Perform ATA Secure Erase if available
4. Fallback to classic wipe 1-pass with zeros if ATA Secure Erase is unavailable
5. Make sure to store progress for current job
6. Sample "after" data (same sample area as "before" data), store it in the results, verify that zeros are read out!

In LCRS2, we ran our own script after building the output. It is run before building the actual images.

The script did this:
https://github.com/fairdk/lcrs2/blob/master/buildroot/postbuild.sh

Perhaps this is still the best and most flexible option. But it should ideally invoke python setup.py sdist to pack an actual distributed version of lcrs-embedded and then pip install it into a complete virtual environment of the host target with all dependencies?

Another option would be if there's somehow already a recipe for installing custom python packages and dependencies on a target system.
