The Ubuntu Release Management Team is pursuing a new concept called "Dangerous" Desktop Images that will ship leading-edge Snaps atop the latest Ubuntu daily development images.

The Ubuntu "Dangerous" Desktop Images will be daily desktop images from the current development series but with all of the included Snaps being from their respective edge channels, for shipping the very newest Snaps atop that otherwise latest Ubuntu desktop development ISO.

Canonical engineer Tim Andersson of the Ubuntu Release Management Team summarized the new "dangerous" desktop images as:

"‘dangerous’ desktop images

We’re currently working on building what we’re calling dangerous images. These’ll be the same as daily desktop images for the devel series, but all of the snaps will be on their respective edge channels. This work is ongoing and there will be more news soon!

These images are intended to help developers who work on our seeded snaps. During the TPM FDE spike earlier this year, all the snaps for daily builds were switched to edge, to help developers. These dangerous images will remove the need to do this in future spikes - one of which starts on Monday!

For those who are unaware, within Canonical we’ve started doing ‘spikes’ this cycle. Spikes are segments of the cycle, 6 weeks long, where members of varying teams join together to focus on one topic, partially or entirely leaving behind their regular daily duties. There was a spike just after the Frankfurt sprint, working on TPM FDE. The next spike, which starts next week, focuses on the desktop prompting-client."
