Sadly not everything works yet. There is much that still needs to be 
tested. And other things break as we go forwards (since the kernel 
community isn't testing with clang yet).

Wonderful! I certainly have told the arch users I meet about your 
packages. :)

The default kernel configs in git are there to give a starting point; 
they largely are there for the current target maintainers (and the 
buildbot) to have something to build and test with (which is mostly boot 
testing still, with some LTP testing). There isn't anywhere near 
complete test coverage however. So the existence of a setting in the 
config file is by no means an indication that something is working. 
That's an ongoing process.

Bug reports welcomed. Kernel patches even more so. :)

I don't think anyone has tried BTRFS yet.

Not yet. But I would love to see somebody build such a wiki page.
