Fix: partitions recently imaged not being detected

jayofdoom · jayofdoom · commit d159aec4f017 · 2014-06-11T16:10:41.000-07:00
When we have just written out a whole disk image, if we do not run
partprobe none of the new partitions show up in blkid, therefore even
images with a built-in configdrive partition will have one created
