Sure, first I'll remove "core" since that terminology doesn't exist
anymore ;)

well, left to its own devices, F9 will see 2.6.26 at least as a testing
kernel pretty soon I think.  Waiting for that seems reasonable vs. the
above patch gyrations....

I think very soon just saying "run the latest kernel + e2fsprogs from F9
updates-testing" will be a good start.  It won't have delalloc yet,
though.  Do we want to try to make that more widely available to people
who can't/don't build their own kernels?  I'm slightly hesitant I guess
both for the extra work of maintaining the repo & complete kernel
builds, as well as providing too much rope to people who may not know
just how much rope they've got ...

For pre-built fedora stuff I'd rather those users just follow what gets
packaged from upstream unless someone really, really thinks we should do
otherwise.
