Comment 1 for bug 670161

I initially only supported this for the not-yet-released Ubuntu 11.04 Natty, but the more I think about it, the more I believe it would be good to reduce the EBS boot disk sizes for existing Ubuntu releases including Ubuntu 10.04 Lucid and Ubuntu 10.10 Maverick.

Reasons for doing this include:

+ 10GB still leaves a lot of spare room for normal system operations (software installation, logs, kernel upgrades, etc).

+ The recommended practice on EC2 is to put data (e.g., mysql files) on a separate EBS volume.

+ If users are already running 10.04 or 10.10 AMIs, they will not be affected if a new AMI is published at a slightly smaller size. The instances they are running and any new instances they run of the current AMIs will continue to be 15GB.

+ The reduced size only affects people who choose to run the newly published AMIs.

+ Anybody who wants to run the new 10GB EBS boot AMI with a larger boot disk, can do so easily:

+ It's not easy to reduce the boot disk size from the one published in the AMI, so this cuts out a bit of the bloat for people who want to run smaller EBS boot disks anyway.

+ It's about time for new AMIs to be published for older versions of Ubuntu anyways to pick up the latest software updates.

+ This would let Ubuntu promote usage of Ubuntu with the AWS free tier using the word "free".
