Subject: [PATCH] image: use du --apparent-size when calculating rootfs size
Date: Thu, 11 Jan 2018 15:18:34 +0000	[thread overview]
Message-ID: <20180111151834.4169-1-ross.burton@intel.com> (raw)

We should pass --apparent-size to du when calculating how large the rootfs is as
otherwise we get the actual disk usage, which if the files are compressed by the
file system (such as ZFS) may be sufficiently smaller than the space required by
the image that construction will fail.
