This thread's top poster is not interested in OTA update from Google.
He's interested in installed community firmware such as LineageOS (formely CyanogenMod).He has no use of the "one partition currently running (with old OS) one partition currently downloading (the next OS)", 1 partition is enough, and wondered if spaces can be claimed from this partition.
In this conditions it's actually relevant to point that the firmware running inside the flash chip will actually claim that unused space as more reserve for wear-leveling.
LineageOS will support A/B updates before those devices (currently only sailfish/marlin) go official. The last hurdle is really backuptool, which allows gapps and other addon.d packages to survive updates, support.
