Author: Dirk Mueller <dmueller@suse.com> Date: 2013-04-03 (Wed, 03 Apr 2013) Changed paths: M build Log Message: ----------- Optimize VM image setup These changes save over 5s on a VM setup phase of a typical armv7l build. Instead of asking mkfs.ext4 to create a journal (which is causing it to do flushed writes of lots of zero blocks) and immediately deleting it afterwards, simply don't create it initially. This alone saves 2s. Prefering fallocate to make use of persistent preallocation avoids fragmentation and small other fixes further speed up the initial build setup phase by several seconds typically.
