as one of the users since the mid 2.0 series. I really think this is the
best approach.

with any 'stable' kernel series I have always had to wait at least a few
days from the release to allow people to report brown-bag problems, and
then I've needed to test it on my particular hardware to make sure there
are no driver gotcha's that happen to bite my configuration, then I can
deploy (either immediatly if it's a security issue, or after load testing
if it's not)

the 2.6.odd/even won't change this at all

the 2.6.x.y will leave me needing to do the same thing for each new x, but
any new .y releases that take place should be able to follow a more rapid
path as they will probably have _very_ few changes in them (i.e. no driver
updates that aren't significant bugfixes). and the ability to do more then
one .y release if nessasary without confusing people is definantly an
advantage over the odd/even approach

good point
