I'm very sorry about this.

Raul and I would have liked to resurrect Rainbow in time for F11-0.84,
and then for F11-0.88. We asked a couple of times about the current
packaging status and what patches still need to be applied in Sugar, but
it seemed that there was still too much integration work to be done.

Don't get me wrong, your volunteer work to enhance Rainbow is much
appreciated, but it is not by itself sufficient to get Rainbow to work
again with Sugar.
There seems to be the need for someone who'd be willing to do the
missing integration work. People with both Sugar and Rainbow expertise
aren't that common.

I wouldn't worry very much: the attack surface of Sugar from the public
Internet is very small: basically, just xulrunner. The LAN of an
elementary school is relatively free of advanced crackers. This leaves
out only unusual Sugar instances that are being used from home networks
connected directly to the Internet.
The worst attack vector I can think of would be a malicious activity. I
think this is pretty much the same threat of malicious Firefox plugins,
and it is being taken care of exactly in the same way. If it becomes
Perhaps I'm not being paranoid enough... but anyway, if the situation
worsens, we could always restore Rainbow and/or check gpg signatures on
installation, like most Linux distros do.

I thought the review got swamped on lkml a long time ago? Or maybe I was
dropped off the cc list... Last thing I know, there was disagreement
about what the correct approach was and some linux hackers derailed the
thread by invoking the stackable LSM bullshit.
What matters the most is that nobody thought that the scenario that your
patch was trying to address wasn't an interesting one. You might have a
chance to get *some* version of your patch approved if you aggressively
reply to the nonsense reviews asking the reviewer:
- how would you do it instead?
- does your alternative effectively address my use-case?
- you and X sent conflicting feedback, please sort it out
among yourselves and let me know which approach is preferred
- who is the authoritative maintainer to ack a patch like this?
In a case like yours, the technical side of getting the patch right is
very easy compared to mediating among conflicting design goals.

0install is a huge leap forward compared to the crap xo bundle format,
but still too much prototypal to cover half of our requirements.
The biggest flaw is that there's no well-defined build system to obtain
binaries from sources, so activities authors would have to setup
multiple environments and build manually for all the architectures we
intend to support. When you add a new architecture, it takes months or
years before most activities become available for it.
I've been advocating a proper build cluster for years. Now that OLPC is
working on an ARM-based platform, it will be clear to anyone why it was
