i tried the current raspberry os bullseye lite arm64 image 2022-09-22. did not work.
spent some time on that.

i then tried the current raspberry os bullseye lite armhf image 2022-09-22. did work.

btw. it would be great if the scripts could work with podman.

ps.
i see that in Prepare a Raspberry Pi device | Mender documentation only hf images are prepared/linked.

copied:

having arm64 images working would be great

Hi @_richard,

Currently we do not offer support for 64bit versions through mender-convert. We are looking into it and plan to add it, but there is no defined timeline at the moment, sorry.

Concerning the podman remark, is there any technical rationale behind it?

Greetz,

Hi @TheYoctoJester,
thanks for the fast response.
I prefer podman a bit for license reasons and not having one more repo to add. The alias docker=podman approach for me did not work in the scripts but it should be possible to provide a param to the scripts that selects docker or podman.

Hi @_richard,

If you think that an optional podman operation mode would bring value to other users, then feel free to share a patch. :+1:

At least from the feedback we get, the license situation of the tooling is not an issue at the moment. My personal experience with compliance problems is way more caused by badly managed golden images and their creation processes.

Greetz,
Josef

thought about that. for now have to focus on other issues.

it’s less a blocking compliance issue then a podman becomes more standard issue.

i understand the “badly managed golden images and their creation processes” issue. For as small test deployment in a somehow controlled context the mender-convert approach looks OK to me.
