I should say that there's also the possibility of writing a block
device plugin which is highly tuned in some way to the Koji use case.
We've already done discarding flushes and showed that you get all the
benefit of a RAM disk just by doing that (even when backed by a disk).

Is there anything else specific to Koji builds:

- Prepopulating the filesystem in the block device?

- Making a block device which is highly tuned to the filesystem it
  will contain (eg. keeping metadata in faster storage)?

- Sharing / deduplicating?

I collected traces of the access pattern of existing Koji builds, but
they are huge and I'm not sure how best to analyze them.

Rich.
