Personally, I would be happier with keeping things like suspend2 in
the kernel, since I don't think the hellish compatibility problems
with non-reviewed kernel functionality that has been ejected into
userspace is really worth it --- but if we *are* going to go down the
route pushing everything into userspace, it is going to be critical
that distro's buy into using a kernel initialization system which is
shipped with the kernel, and can be updated without being tied a
particular distro's non-standard "value add". Maybe that means we
need to have hooks so that the distro's can add their non-standard
"value add" without breaking the ability for users to upgrade to newer
kernels.
we're going to go, and if we're going to go down the blind
in-userspace-good-in-kernel-bad approach, the distro's are going to
have to cooperate or it's going to be a mess.
