Then work with whatever WM you want to help them support what makes sense
for them. For instance, I use Enlightenment but most of the crap proposed
in Reiser4 doesn't make sense for E because there's no filemanager or
anything. The image thumbnails in metadata might be nice, but I wouldn't
throw a fit if the current runtime generated thumbnails were still used.

Nothing has happened so far, once the VFS extensions are laid out,
documented and implemented we can begin to start saying that some of the
features are fs agnostic.

I'm not advocating a fork, I just think it's stupid that so many people
have been saying "Stop arguing, just accept reiser4 as-is because it's
fast and cool!!!!"

People have been saying the same thing about reiser3 for years and yet
every time I break down and try it again for whatever reason I find a nice
new corner case that causes me headaches and usually ends up in me going
back to ext3 or XFS.

Right, because Hans is so damned receptive.

I'm not buying it, but only time will tell.

I don't disagree, there are many aspects of each section of a Linux distro
where decisions can affect how Linux is perceived by current and new users.
But IMO not letting reiser4 in, in it's current state, isn't going to send
a bunch of Linux users running to get Macs.

I understand why he wants to have his marketing pages and I don't care if
they exist, but you would think he would also want to have some SDK-type
pages where it explains the new features, the "plug-in" API and such.

But if big VFS changes are going to happen, I doubt anyone would want to
make them in -linus or -mm because there's probably going to be a lot of
initial breakage. Maybe this would be a good reason to fork 2.7?

I agree, it was interesting for the first few days but now most of the
threads have gone so far OT that it's just stupid.
