Yes, I read it. Nigel already replied and pointed out that a lot of
things were already fixed and will now be. So the effort to make the
patch acceptable is there.

However, about the User-UI stuff and some things that are implemented in
the kernel, I have to disagree with you. Suspend 2 happily works without
having the userspace UI, which is a good thing as it allows a minimal
setup and a small initrd.

But besides the progress bar I think that some parts have to be in the
kernel, such as the warnings and keyevents to abort the progress. If,
for whatever reason, something goes wrong, you should be able to stop
and abort before doing any damage. If all these things are implemented
in userspace, you need to have a binary in your initrd on the right
place, where is should work without that.

Matthias
