I build a prototype implementation of this now that should be ok for public testing. The idea discussed with Evan Dandrea (and others) was to create a writable overlay into /tmp on top the systemdirs in / and then run the release upgrade. This way we can test easily if the system would upgrade cleanly (if no dpkg errors/maintainer script failures happen). All writes go into /tmp so after the upgrade and on the next reboot the system is back to its pre-upgraded state again (modulo /home, that is not overlayed). It also means the next boot takes a *long* time to clean /tmp - when I did test it on one of my production machines that wait made me *really* nervous :) But its ok, it just takes long (up to ~20 minutes or so). Feedback is welcome This idea seems like a really nice idea, and one that in some other form is requested by users/testers. I would like to add to points: * if all tests go OK, and we end up with this on koala (to late for FFe on jaunty, right?), a checkbox when using update-manager -d / cli question on do-release-upgrade to use Sandbox would be much nicer then running all that code. * to save the system state prior to upgrade, so that a user can restore the system if even after successful package upgrade, some application/kernel/driver upgrade doesnt go as good. I am a bit on the short end of this topic due to trouble with having this set to digest mode. What exactly is this going to do. It sounds very interesting. is this similar to system restore in windows? The following quote makes it sound like after reboot it is going to restore itself to before the latest upgrade: All writes go into /tmp so after the upgrade and on the next reboot the system is back to its pre-upgraded state again Doe the above always write to /tmp? If so does it clear upon restart automatically?

Re: aufs based upgrade tests
When doing something like this one should be careful because here you have a copy of all files that are modified during the upgrade. Applications keeping these files open will write to the old copies, and applications which reopen the file after the upgrade will not see this data. This may be dangerous and lead to unexpected behaviour. Apart from that, as I ranted in the past, let me say that this is a very important change and I am really happy that ubuntu developers are making it happen.

I always loved the power button in its own corner (and the same corner where you close windows) because it gives the feeling of a physical machine, e.g. a home hi-fi with its own big red button. I didn't follow the recent discussion on fusa and all the rest but... well, the button with its icon was nice and intuitive.

GTK+ 2.16 in Jaunty?
Sorry, this sort of question gets asked all the time but at least it's a change from the will you package Firefox 4 Alpha? type :P So, GTK+ 2.16 was just released and there's already an app I can't compile: Epiphany 2.27! Bit of a shame when I'm running Jaunty. The release adds some new features, including a warning on the password field when the user presses caps lock, an improved file chooser and the ability to add icons to text entries. (Other really good things, too, but I shouldn't restate the release notes). Polish, basically, and lots of it. With those features, I get the strong suspicion that lots of apps will quickly come to depend on 2.16. Is it possible this will hit Jaunty by any means, or should I start installing from source?

Thanks, Dylan McCall Hi Dylan, Yes, I believe Jaunty will ship with 2.16. Jaunty is currently using 2.15.5 which is a development release leading up to 2.16, so it is reasonable to assume that Jaunty will have 2.16. 2.16 was only released on Friday and it is still the weekend at the moment, so it's probably a little unreasonable to expect it to have been packaged already. I'm sure that this is something that someone will work on early this week.
