From d4e8653e1e9ec90404d12ea24fb0f8e507b337d5 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Tue, 9 Jan 2024 19:54:51 +0000 Subject: [PATCH] mvebu: puzzle-m90x: wipe rootfs_data on sysupgrade The sysupgrade formware of the Puzzle series is a slightly strange dual-boot approach while remaining compatible with Marvell's SDK firmware upgrade binary format -- which happens to be a full-disk image with GPT partition table. Hence that /lib/upgrade/emmc-puzzle.sh script is like an exotic disease which results from those decisions, and as we also want to somehow stay compatible with the IEI-World stock firmware we got to use it in that same way (we are not compatible with the QNAP-branded identical hardware device anyway). Currently, on sysupgrade the result is that one ends up with the old content of rootfs_data (a GPT partition on those devices) as nothing ever wipes or in any way re-creates the filesystem there. As a simple work-around, let's kill the filesystem on rootfs_data so fstools re-formats it on the next boot.
