Create AMIs with full 10GB root partition

[Eric Hammond]

This request does not really belong against the vmbuilder project but rather applies to the Ubuntu images being built. They currently have 4GB root partitions (4096) which is arbitrarily and unnecessarily limiting.

These images should be built with the maximum 10GB root partition (10240) allowed by EC2.

Justification:

The increased root partition size does not materially increase the size of the AMI and does not materially increase the startup time.

It is not possible for users to alter the size of the root partition in an AMI.

Having a small root partition limits how much software users can install easily. It also limits basic operations in software like MySQL using the default configuration (e.g., tmpdir, datadir).

I originally built Ubuntu AMIs with 4GB root partitions in early 2008 but switched to the full 10GB based on user feedback and my own experience.

I agree we should increase this, and I think it's perfectly appropriate to change before final release.

I made the above comment, but forgot log in as myself after setting up the bot. Sorry about the confusion.
