So, I give it some thoughts over night and here is the blockers for that option
as far as I can see:
Take in mind that's the very first step of the session deciding on which
session "flavor" we are jumping into, launched components being dependent on
that.
- Policykit is indeed unavailable at this step, so launching an install
(without any window manager), with a dialog asking for your password to
get right privilege to install the package isn't quite straightforward.
- NM as well isn't available as well as gnome-keyring. And that's the
main blocker IMHO: Indeed, the keyring contains the Wifi passphrase. I
think the laptop/netbook over Wifi here is one of the main target and it
won't be able to connect at this stage then. Even if we (by some tricks)
delayed the installed to get those two services started at first, there
will be an issue at first run. The dialog will be shown with "do you
want to download unity2d", but at it's the first reboot after
installation, the network settings being correctly filed by the user
yet. So, it's more a less a lot of people won't be able to enjoy the
feature.
- If we are going to the path to ignore latest concern and just try to
launch all service before switching to the new "session type" installed,
gnome-session doesn't make dynamically switching to session type easily.
Even upstream tried that for gnome-shell and postpone as they got a lot
of ackward side-effects.
Is that all and not possible? Well, I would say that for this cycle and at this
stage of the release, we have two options less risky:
-> 1st one is to launch software-center on the unity2d page, then, the user has
time to file his internet settings, and all services to start (the only thing
is that we have to ensure avoiding doing that on the live cd)
-> 2nd and the one which make more sense to me, is to include this question in
ubiquity if we detect that it can't support unity (the tester is an binary
which is available on the live). I proposed a similar option (additional
question for nvidia user) at latest UDS. The preferred way was to add that to
the "proprietary addon" (like mp3) checkbox, but I think that an additional
dialog can make sense for installing unity2d in desired case and will make even
more sense.
What do you think?
