Comment 11 for bug 1879350

I have just fired up a livefs build of ubuntu-core on focal (UC20), without the snappy PPA and with -proposed enabled, with CHANNEL=dangerous-beta:

https://launchpad.net/~ubuntu-cdimage/+livefs/ubuntu/focal/ubuntu-core/+build/229423

The build succeeded and the model-assertion used is the dangerous-edge one, which is what was expected (as there is no dangerous-beta assertion). By looking at the image manifest I see that the core20 snap is indeed taken from beta, so the channel override happened successfully. In other words: the build ended up generating a dangerous beta-based image, as expected.

The build used livecd-rootfs 2.664.3. Considering this verified.
