In particular the "complexity" column is a bit subjective. Stefano, I

No worry...and I have not written myself. It was inserted by Mariano, so
it looks like that swupdate at least for Mariano is "easy to use".
I think it is correct to point out that customization is required.
Compared to other update mechanism that I tested it was the easier to
implement.
Which "getting started" document or presentation were you using? The
documentation for mender (https://docs.mender.io/) is very
straight-forward (partly of course because it doesn't need to cover many
variations), while for swupdate
(http://sbabic.github.io/swupdate/swupdate.html) I found it less clear
how to begin.
When I did a research in update mechanism, mender wasn't yet available,
and indeed it seems very straight forward (need to test it before final
veredict). But if you compare SWUpdate, swupd, and OSTree; SWUpdate is
by far less complex than the other two
Ease-of-use is not necessarily determined by the complexity. Good
integration and documentation can go a long way towards making a complex
solution easy to use - when sticking to the pre-defined usage patterns.
The opposite is also true: a simple solution may be hard to use if all
one gets is the source code and one first has to reverse-engineer the
usage model.
Completely agree with you Patrick, it could be a simple solution very
hard to use because of the lack of documentation
I agree that the complexity is roughly swupdate < ostree < swupd and
there's also no doubt that the latter two aren't easy to use (mostly due
to lacking documentation and integration), but I'm still not sure what
documentation the "easy to use" verdict for swupdate is based on.
I based my verdict using this source:
https://sbabic.github.io/swupdate/
You can follow this and create your update image few hours.
Cheers
Mariano
