From 29bc2f74239bc98a152605c339b8a4fb0a15705b Mon Sep 17 00:00:00 2001 From: Joshua Lock Date: Fri, 8 Apr 2016 10:14:18 +0100 Subject: wic/utils/partitionedfs.py: assemble .wic images as sparse files The individual partitions created by wic are sparse but without this change the assembled image is written as one (potentially very) large file. Preserve sparseness in the assembled image by passing the sparse conversion symbol.
