Yes, it is used for Steven's recent F11-XO1 releases

Yes, it has been used for all recent XO-1.5 OS builds which are partitioned.

I don't know what the effects (if any) would be if you tried to build
10.1 from non-F11, I have not tried but I don't think its a good idea,
hence the warning. Investigation welcome.

You also need to match the olpc-os-builder version to the build that
you are making, since some of the sauce that makes the build is
specific to the build scripts at a certain point of time. This
specific point might have been overlooked for 10.1.1 - is it
officially released? If so the olpc-os-builder tree should be bumped
and tagged as v1.1.0 at that specific point, and suggested_oob_version
in the 10.1.1 build config should be set appropriately.

Yes - as has been true for all OLPC OS releases to date. Nothing has
changed in this respect with the new build system. (although that
server does have some stability issues)

The idea is to get this into Fedora to make it dead easy for deployments:

Then these instructions can be followed:

Someone needs to pick up that work, maybe you? :)

In addition to the docs that Chris pointed out, note that all modules
have a README too.
