* wic: use truncate utility to create sparse filesEd Bartosh2016-05-061-15/+5
| | | | | | | | | | | | | | | | | | | Used truncate instead of dd to create wic images for the following reasons: - dd doesn't preserve sparseness - truncate syntax is much more clear - dd requires additional calculations of the image size in blocks - the way dd was used in the code is not always correct. In some cases it was writing one block to the file which makes it not 100% sparse.

* wic: add system_id attribute to PartitionEd Bartosh2016-04-291-0/+1
| | | | | | | | | | | | | | | Added Partition.system_id attribute and initialized it from parse result of wks option --system-id. It will be used by the wic code below the call stack to set partition system id.

* wic: don't throw away our created swap partitionChristopher Larson2016-02-281-0/+1
| | | | | | | | | | | | | We were creating the partition, mkswap'ing it, and then not dd'ing it into place in the final image, as source_file wasn't being set for swap partitions. This would result in a swap partition that couldn't be enabled on target until mkswap was run.

* wic: fix processing of --use-uuidEd Bartosh2016-02-151-0/+3
| | | | | | | | | | | | | | | Processing of this option was lost during recent change of wks parsting. It was discovered during the work on booting wic images under qemu. Now, when -use-uuid is fixed it's possible to specify root partition by partition uuid. This will be done in the following commit.

* wic: add partition moduleEd Bartosh2016-01-181-0/+410
Copied partition-related API from kickstart/custom_commands/partition.py to separate module in preparation for removal of all pykickstart related code.
