I have a concern that ad hoc scripts like this will break in the future.
You should test before using it in production for each release. For example
grizzly changes how kernels are named and this could break that script. I
personally think if you run adhoc scripts from outside the nova codebase,
then the onus is on your to understand the underlying code and what the
script is doing -- the nova developers can't maintain things we don't know
about.

Have you tested the fixes that were put into trunk several months ago for
those problems? The cleaner is on by default in grizzly, so testing before
release would be a good idea.
