From 6dd32f4a3bf29605f7b8fb6e1d801628310fcfd3 Mon Sep 17 00:00:00 2001 From: Claudius Heine Date: Thu, 10 Mar 2022 14:13:29 +0100 Subject: files: overlayfs-etc: add overlay mount options to preinit Overlayfs-etc is useful if the rootfs is read-only. One reason to have the rootfs read-only is to allow image based updating. Image based updating will change the underlying root file system, which is unsupported by overlayfs when with some mount options [1]. This disables those options.
