You have to do OTA software updates for your Yocto image so what does the process look like? The first thing is deciding what kind of update you want. As a user you might tend to think immediately about RootFileSystem updates for operating the whole file system. This is a good choice for many. But not necessarily for all users. There are other kinds of updates that you can do, such as updating containers. It is very common now to run Docker and update the entire roof file system just to update a container. But this might be something of an overkill as it’s going to use so much bandwidth and take so much time. It can also wear out your flash memory very quickly. So thinking about what you want to update is the first thing you should do.
