As for Reiser4, they're fixing the code now to look more Linuxy
and all's well.

The discussion is "Should the VFS be extended to support files-as-dirs
or data objects by using what we already have in Reiser4 in -mm, although
disabled."

And people who'd like to use something lighter than Gnome or KDE
and still use these nice features?

They would not be tied to a single filesystem, naturally, I think
we can all agree that case is closed, as it'll just spawn another
waste-of-time flamewar.

It'd be much better to talk this thing through..
There have been pretty good arguments for the extended VFS, that it
would be doable. It may just be less of a unix after that, or less
of Linux as we know it now.

The circular reasoning "We don't want Reiser4's files-as-dirs in
before they're tested. We also have them disabled by default.
They should not be implemented on this layer here, but we won't
let you touch our VFS." is bad.

Surely if the things started to go into the VFS in a separate,
official tree, it'd no longer be just Namesys doing the work.

The filesystem is tested well enough to go in. For real.
It may not be production stable with immediacy but it is tested.

The extended semantics are a separate matter.

Then someone steps up and goes "No, shut the fuck up and fix the code,
we gave you your shot" or something.

Community pressure.

And it'll be a lot easier with the new VFS.

Sometimes it also seems people would much rather shout at each
other than see that reasons are starting to pop up why Linux
could lose popularity.

I accidentally deleted the paragraph with you saying the page
reads like a commercial.

I half agree, Hans has written that well, but maybe for
people who would pay him money to do his work.
Therefore some of the stuff is a bit obscure. Like what is now 
Reiser4.1 (ie. ..metas/ whatever, I believe) is apparently referred 
to as Reiser6 there.

It'd be damned nice to see that page revisited a bit, maybe not much,
but getting the names straight and having one of the tech guys write
tech documentation that's clearly accessible.

That page does still not change the situation that the code exists
to some extent, which could be merged to the VFS layer by
extending it a bit and this would be easiest done in a tree that
people will want to hack on.

And frankly this amount of tautology is starting to get even 
on my nerves :)
