Comment 4 for bug 1765933

The status of this bug is accurate. Please see the linked merge proposals for more information; the current blocker is me dealing with a complex set of review feedback on https://code.launchpad.net/~cjwatson/launchpad/+git/launchpad/+merge/373971. After that, it will still remain for somebody to work out how to integrate this usefully into livecd-rootfs.

As far as I know, nobody has yet worked out how to eliminate magic-proxy entirely. What the pending Launchpad work will give you is a mechanism to query Launchpad for the state of a given metadata file in a given suite at a given point in time, which provides enough information to start the process. However, until PS5 exists (and a significant amount of development work on top of that) we won't actually be able to provide snapshot archives that are directly usable by apt, so livecd-rootfs is still going to have to do a fair amount of massaging of live-build, and somebody needs to dig into the exact details there.
