But it's not (IMO) a BOOTC_ALEPH_ anymore right? We've just made up a new file name that's used as a kind of hidden API between osbuild and coreos and bootc right?
While it's accessible via git log anyways, I think the comment here should link to the FCOS tracker issue is I believe that's the canonical thing defining its existence/rationale - it's not directly part of this project.

I guess I'll just keep repeating that I feel like the aleph stuff was a mistake, but we've also spent way too much time talking about it relative to its importance; cc coreos/fedora-coreos-tracker#2187 (comment) So anyways LGTM after issues above are addressed |

I would have factored out a little symlink_idempotent helper, something to do for the future

I just did that while addressing the missing DCO and other linter complains :)

It will no-op if the symlink already exists and already points to the correct target, otherwise re-create it. Signed-off-by: Jean-Baptiste Trystram <jbtrystram@redhat.com>
This adds a compatibility symlink along the created `.bootc-aleph.json` named `.aleph-version.json`. This compat symlink allow for an easier migration from osbuild's aleph stage [1] to the aleph provided by `bootc install`. This also create a precedent for a "standard" aleph well-known filename that isn't tied to the name of the tool creating it. Note that coreOS and bootupd relies on this aleph file to exist.

Sorry I meant that's something we can do as a separate PR, didn't have to block this one. |
