This is an attempt to fix issue #237 The script "growpart" was added as an asset, because Debian's Jessie version (inside cloud-utils) package is outdated and buggy. Then "expand-root" init script was modified to call growpart before calling resize2fs. In fact, calling resize2fs without resizing the partition first is useless. The task was named 'AddWorkaroundGrowpart' because it must go away in the future in favor of using recent stuff in cloud-utils. Currently even the official images suffer this issue, that makes the system use only 8 GiB, even if the user chooses a bigger storage size inside AWS.
