It seems to me that we all have a large investment in the inner workings
of the Linux kernel. The more cleanly it works, the better for us; the
more maintainable and accessible the code, the better for us.
Conversely, if the kernel ever gets overwhelmed by cruft or becomes
either unmaintainable or inaccessible to those developers who're sharing
their labor with us, we all lose a large investment of time as we battle
the inherent instability in such a system, not to mention the time we'll
spend researching which platform to leap to next.

In the end, I'll consider the kernel developers to be the experts as
it's them I want to be pleased with the end product. If they're happy,
I'm happy. Mostly.

No argument here. I like options. =]

Off-topic semi-rant: We should *always* consider alternatives, if only
to educate ourselves. Not doing so creates catchphrases like "Nobody
ever got fired for buying IBM," and "Microsoft-compatible."

XFS is indeed lovely; I'm an IRIX fan from way back. And, to be clear,
if and when it's accepted into the mainline kernel tree I'll look it
over to be sure it's behaving well in its new home and, if so, I'll see
where it makes sense to use it. 

In the meantime, it's very important to note that it IS available, it's
just that the price is to maintain your own patched source tree and
compile your own kernels. If you don't want to pay the price of your
time, is it really worth that much to you?

Me, too. In the meantime, e3fs is working just peachy. =]
