It won't help for 5-7 years (customers use downlevel versions of RHEL
for a ****long**** time) --- one of the things I most enjoyed when I
moved from IBM was Google was the knowledge that I could make an
improvement in the kernel, and have my customers start to benefit from
that change in less than 3 months.... as opposed to being at the mercy
of Red Hat and SuSE's arthritic kernel update/release schedules. :-)
But it seems to me that making cloud-init to use some kind of plug-in
architecture would be really helpful, even if it's not going to be a
solution for the immediate future. That, and cloud-init *badly* needs
to get away from the "run-and-done" model.

"Run-and-done" also doesn't support disk snapshots and disk resizing
properly.
