I think the command-line is far more flexable then the GUI interface. I use ec2-api-tools, but the python boto stuff works virtually the same.

...nd use those directly as a file system. The result is that if you elect to allocate a larger base disk image, for example allocating 50 Gig to allow local home directories or space for "mock" or for bulky logs, and don't spend the time to select and allocate new disk images, it's awkward to simply expand the "/" partition. And with only 8 Gig allocated in the latest CentOS 6 images that I see in AWS, it's possible to get pretty pressed for space pretty quickly. Now, AWS published guidelines on manipulating partition size, and expanding a matching filesystem, but the...
