Subject: [DistroKit] [PATCH 13/14] image-rauc: use ext4 rootfs instead of tar.gz
Date: Fri, 23 Jun 2023 14:47:54 +0200	[thread overview]
Message-ID: <20230623124755.2292833-14-rhi@pengutronix.de> (raw)
In-Reply-To: <20230623124755.2292833-1-rhi@pengutronix.de>

On one hand, the squashfs inside the RAUC bundle already uses
compression, so with a tar.gz inside a squashfs the content is
compressed twice. Also using ext4 makes it possible to use adaptive
updates in the future.

(Yes, the image generated by the image-root-ext recipe is really called
"root.ext2", even if it's an ext4 image.)
