I’ve got a few questions regarding updates and best practices for the PiAware SD card build. I’m using 3.6.2 which I deployed as a fresh image. I searched for answers to these but drew a blank so I’m asking here so there’s a reference for future users. I have auto updates disabled as I prefer to have manual control over updates to active systems.
The current version is 3.6.2. Before that was 3.5.3. Is there a format to these numbers? For example would a minor update to 3.6.2 be 3.6.3?
I had 3.5.3 since Nov 2017 when I joined and I never updated it until I overwrote it with 3.6.2. Obviously there would be OS updates in that time, some of them important and urgent. Should I be doing apt-get update+upgrade on the SD build? If not, is there some other way to get OS updates on?
On my site admin page I can send an “Upgrade and restart PiAware”. There is also an “Upgrade and restart dump1090” (which I assume means dump1090-fa). When would an upgrade using these options be needed? Would they be used to search for and install ongoing updates, as in the previous question, or are the specifically for installing a new release of PiAware, such as when 3.5.3 was replaced by 3.6.2? When would the dump1090 upgrade option be needed?
If I have auto updates enabled what kind of updates will be installed and is there a schedule for them? As with the previous question would these be ongoing OS updates or just an automated way to move from the likes of 3.5.3 to 3.6.2?
