discover: Add 'sync' user event
Add a user event named 'sync' that causes the discover server to merge the devicemapper snapshots of mounted devices. This is particularly useful as a debug aid (for example, when copying logs to a USB device), as the server will otherwise only sync changes to mounted devices in response to parser actions. The command can be called as pb-event sync@device to sync a particular device, or as pb-event sync@all to sync all devices with snapshots. Signed-off-by: Samuel Mendoza-Jonas <>
