Graber: LXD now re-licensed and under a CLA

The story of Canonical's takeover of the LXD container manager, and the
subsequent creation of the Incus fork, has been
simmering for a while. Now Incus developer Stéphane Graber reports
that Canonical has changed the license and contribution terms for LXD:

Per the commit message performing the re-licensing, all further
contributions will be under the AGPLv3 license and all
contributions from Canonical employees have been re-licensed to
AGPLv3.

However, Canonical does not own the copyright on any contribution
from non-employees, such as the many changes they have imported
from Incus over the past few months. Those therefore remain under
the Apache2 license that they were contributed under.

As a result, Canonical cannot release LXD under the AGPLv3 license
and likely never will be able to. LXD is now under a weird mix of
Apache2 and AGPLv3 with no clear metadata indicating what file or
what part of each file is under one license or the other.

He also notes that this change will put an end to the flow of patches — in
either direction — between the two projects.
