I am trying check my understanding before deployment.
- how mender downloads the update. Is it done in parts or is it one single download? It looks like it is one single download.
If I have an update which is 300 MB in size and is midway downloading, If I power cycle the unit and I have the retry set to 0 the update fails
2. Can I change my certificate and hosted mender api via a artifact update
- Do I have to include anything specific to perform an rollback. I think there are two conditions
a. Normal delta update on the root file system update. I see that if the download fails then we don’t perform the update
b. But in the scenario where I have created my own specific state scripts then its my responsibility to create a rollback script and include it in my artifact update in case the state scripts fails?
