From: Petr Štetiar Date: Wed, 27 Mar 2019 10:31:14 +0000 (+0100) Subject: x86: image: remove TARGET_IMAGES_PAD option and force padding X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2109156b794fd94a94df358afad860bffc72d9d3;p=openwrt%2Fstaging%2Fjow.git x86: image: remove TARGET_IMAGES_PAD option and force padding Currently we're producing unusable x86 combined squashfs images (18.06.1, 18.06.2 and snapshots) as we don't enable TARGET_IMAGES_PAD, thus providing very small space for the overlay filesystem, leading to the following with OpenWrt 18.06.1 r7258-5eb055306f images on x86 QEMU: root@(none):/# mount | egrep 'root|overlay' /dev/root on /rom type squashfs /dev/loop0 on /overlay type ext4 overlayfs:/overlay on / type overlay root@(none):/# df -h | egrep 'root|overlay|Size' Filesystem Size Used Available Use% Mounted on /dev/root 2.5M 2.5M 0 100% /rom /dev/loop0 113.0K 8.0K 97.0K 8% /overlay overlayfs:/overlay 113.0K 8.0K 97.0K 8% / We should rather ensure proper image padding in image generation code and we shouldn't rely on config options in order to generate usable images. So this patch removes TARGET_IMAGES_PAD config option and enforces padding on combined images.
