Its a little more complicated than that. Really what we're most concerned with, is making
sure that we direct users to a usable Cassandra solution. While having it as a source package,
with all of its dependencies shipped as source packages is attractive from a long term maintenance
point of view, we certainly don't want to ship something that will leave users with no upstream
support in a year.

MongoDB is in a similar state in Ubuntu, where the version shipped with Lucid wasn't even
recommended as the version to run when Lucid released. This doesn't mean it is unusable, but
it does mean the user is pretty stuck now, and upgrades at the end of the LTS cycle may be
quite difficult.

It seems that a better path to take would be for us to make it easier for users to find and
utilize the current Cassandra packages until such time as development slows, and we can ship
a version that we know will still be useful 1 - 2 years post release.

So for the time being, I think we'll pass on re-packaging Cassandra, and packaging the dependencies
for the impending 10.10 release, but when the effort to get Cassandra and its dependencies
into debian unstable gets under way, we'll hopefully be able to throw some cycles at it. I'm
particularly interested in making it easier to build debian packages / dependency information
from the contents of ivy.xml, as that would reduce the amount of manual work required with
each release.
