Now that we are able to store security labels for devices, next step is to flush them into a file. For more convenience I've chosen JSON format (as we have all the APIs needed for processing the format).
I wonder if we're better off avoiding using a structured file format entirely. IIUC, we essentially just need a boolean indicator for the udev helper against each device. Could we do this with a zero length file per device. eg consider a device '/dev/sda1' That has a sha256 checksum d8d8d2c47b672edb91407c0014286b472673b2ff9d6636fd567d11650986ba3c so we could just touch a zero length file /var/lib/libvirt/udev/$CHECKSUM that way the udev helper doesn't need to parse anything - it merely needs to see if the file exists or not.
