initramfs-framework: overlayroot: align bootparams with module name

2024-02-19T14:56:23+00:00

Renaming the 'rootrw' kernel commandline parameter to 'overlayrootrwdev' to both align better with this modules name, and point out the usage of the variable. This patch also includes an if block to migrate the old 'rootrw' block, should it be already used by someone.

initramfs-framework: overlayroot: fix kernel commandline clash

2024-02-19T14:56:23+00:00

The initramfs-framwork takes kernel commandline options and converts them for internal use to variables following the 'bootparam_name' pattern. The overlayroot module uses 'bootparam_rootfstype' and 'bootparam_rootfsflags' which both collide with linux kernel parameters 'rootfstype' and 'rootfsflags'. This collision is solved by putting the variables in the namespace of the initramfs-framework module.

initramfs-framework: move storage mounts to actual rootfs

2022-06-21T17:44:27+00:00

Operations such as mkfs fail on devices that are not switched to the actual rootfs before switch_root is called. The kernel interprets these devices as still being used even after unmounting and errors such as below are seen when the target is fully booted root@v1000:~# umount /dev/sdb1 root@v1000:~# mkfs.ext4 /dev/sdb1 mke2fs 1.43.8 (1-Jan-2018) /dev/sdb1 contains a ext4 file system last mounted on Wed Nov 28 07:33:54 2018 Proceed anyway? (y,N) y /dev/sdb1 is apparently in use by the system; will not make a filesystem here!

initramfs-framework: Add overlayroot module

2022-03-01T23:44:59+00:00

When installed, this module mounts a read-write (RW) overlay on top of a root filesystem, which is kept read-only (RO), free from modifications by the user, this might prove to be useful if we want to access or restore the original unmodified rootfs. The existing overlay-etc.bbclass does something similar, it mounts an overlay on top of the /etc directory, however doing the same for root causes the original root to be inaccessible once the system is booted, hence why this module is added to the initramfs boot flow, allowing us to mount the RW overlay, while keeping the original rootfs mounted at /rofs once the system finishes booting. This script is loosely based on that class. This module requires rootrw= to be passed as a kernel parameter to specify the device/partition to be used as RW by the overlay and has a dependency on overlayfs support being present in the running kernel. It does not require the read-only IMAGE_FEATURE to be enabled. The module needs to be executed after the initramfs-module-rootfs since it relies on it to mount the filesystem at initramfs startup but before the finish module which normally switches root. After overlayroot is executed the usual boot flow continues from the real init process. If something goes wrong while running this module, the rootfs is still mounted RO (with no overlay) and the finish module is executed to continue booting normally. Its worth noting that, on purpose, this isnt installed by default on any images that use initramfs-framework to keep the boot flow unmodified, only when a user manually requests to install it, then it becomes functional.

initramfs-framework: unmount automounts before switch_root

2022-02-12T17:05:35+00:00

If mounts are left lingering, then after we switch_root, attempts to modify the block devices will result in an EBUSY with no way to unmount them. As we're about to switch_root anyways, there isn't much use to keep anything mounted unless it has the new rootfs.

initramfs-framework: support kernel cmdline with double quotes

It avoids init to crash when kernel cmdline contains a string with spaces inside, like that: dyndbg="file drivers/usb/core/hub.c +pltf" (From OE-Core rev: 88b8b94bd2d052bca29d27bd5cd00eddb0f5999d) Signed-off-by: Christophe Guibout Signed-off-by: Richard Purdie

initramfs-framework: check successful mount using mountpoint

2020-06-09T12:13:59+00:00

Instead of checking for existence of /dev in the mounted file system use mountpoint to check if a root file system has been mounted. This allows to use the rootfs module for OSTree based rootfs as well, where the file system rootfs does not have any of the regular directories (at least when using the modern layout).
