Yes, I agree. Both with this being a good solution, and with that it will need
a lot of work.

I suppose the most important thing is to get the Debian native packages
updated with new features from 5.5.32...35, I suppose it's mostly new storage
engines?

If the work turns out bigger than available resources, and I had to choose, I
would choose to break upgrades from the legacy 3rd-party packages. If we can
get good native Debian packages, and new 3rd-party packages based closely on
that, then I think it is worth it to break upgrades once (users will have to
eg. apt-get remove the old stuff and apt-get install the new, once).

Of course, if we can make everything work, then so much the better. My point
is merely that I would put priority on getting everything right moving
forward, and only solve the remaining single upgrade once the prio stuff is
done.

I can try to find time to setup this, but I will need an exact list of the
commands that should be run. Basically, you need to provide a script that can
be run in a clean VM and does what you want the buildbot to do. It doesn't
have to be fancy, but it needs to be complete so that it is clear what needs
to be done.

Daniel, can you prepare new sets of VMs for Ubuntu trusty and Debian sid?
Then I can try to setup Buildbot to do these builds.

I think so. It is not clear to me who can do what, but the plan is good.
