Began work on S3 backed instances. Refactored adding tasks. Got stuck on the bundle image call, it uses argparse. Somehow we need to fake the arguments. 2013-07-13 15:10:04 +02:00			`from base import Task`
			`from common import phases`
Support for partitions MAJOR refactor. The volume is now abstracted into a model along with a partitionmap and partitions. Volumes and partitions are now controlled via an FSM to ensure that commands are called in the proper sequence. GRUB can now be installed properly onto loop devices by using dmsetup to fake a proper harddisk. 2013-09-15 13:19:45 +02:00			`import volume`
