Bug Description
I just ran a simple single instance launch, and on raring i saw:
cc_resizefs.
on precise:
cc_resizefs.
Those are real time reports from /var/log/
up to 10G root from the ~1.4G that the images have built in.
This is known-fixed in current versions (quantal and later).
The changes were done to upstream e2fsprogs under debian bug 663237.
Bug 978012 is a general request for a newer e2fsprogs, and this bug is a specific request for the performance improvements.
Related bugs:
* bug 978012: Please SRU micro bug fix release of e2fsprogs 1.42.4-3ubuntu1
(main) from Quantal (main)
* debian bug 663237: Make resize2fs shrinking use much less CPU

I have a branch at lp:~smoser/ubuntu/precise/e2fsprogs/resize2fs_performance/ where I think I cherry picked the fixes, but haven't done much testing yet.
Attaching a cloud-config that can be hopefully used to test this change, by adding the repo and then doing the resize after update/upgrade has occurred.
