There is no contradiction in the two statements. To attempt to
estimate something I don't need a reliable sample of the whole
population. Estimation is still a statistical thing. Also I said
attempt to estimate, it doesn't mean I will make it.
If you don't consider those results a positive for reiser4, it can
only mean you expected reiser4 to have a much higher share among the
KLive users. This is obvious.

If they say "1:5 ratio for reiser4:ext3 KLive users" everything will
be correct and nobody can object because it's a fact.
I said myself that I'm no reiserfs user, and I don't plan to become
one any time soon (especially on my production systems), I'm only
reporting plain numbers as KLive measured the stuff. I'm surprised as
much as you are, but then I've to report facts, and not my own
opinions.
As far as I'm concerned the thing I like less of reiser4 is the plugin
thing, I'd be less concerned if that was a microkernel (fuse-like)
userland plugin system. Anyway with time perhaps things can change and
become userland based, and the stuff can be moved into vfs if that
code really belongs there as some kernel developer says. That doesn't
mean reiser4 can't be merged first and the stuff moved into vfs
later. xfs when was merged also pratically rewrote a vfs internally
that was meant to work with irix, if Christoph didn't complain about
xfs being merged, I don't see what's the problem of reiser4 being
merged even if it rewrites some part of vfs. xfs is also still having
various special features like the pinhole one that only belongs to the
vfs instead but nobody complains.
And if reiser4 is really so bad as they say, once people starts losing
data they will spread the word of not using it. As long as it's marked
experimental I don't see a big issue, the wireless driver for broadcom
chip will eat your filesystem too if the reverse engineered dma
operations writes into a buffer header instead of an skb.
