initramfs-framework:configuration to boot up live image
v5 cover initramfs-framework:configuration to boot up live image
From: "Ng, Wei Tee" <[email protected]>
Hi,
This patch is to get initramfs-framework able to boot up live image. A new scriplet named setup-live module has been created to handle the removeable media detection and assign the rootfs.img. This is because the current rootfs module has no support for rootfs images, only rootfs partitions.
This version 5 included the changes for re-correct the indenting issues and squashing 2 commits into single commit. It involve the creation of initramfs-module-setup-live in the recipe and added udev-extraconf rdepends on this module because it is needed for automounting process.
This changes has been verified with build test and boot up test on Minnowboard Max platform.
Please review and provide feedback if you have any. The patches are targeted for merging into poky master branch.
Thanks and regards,
Wei Tee

PATCH v5 1/1 initramfs-framwork: module to support boot live image
From: "Ng, Wei Tee" <[email protected]>
setup-live module is a new module being introduced to integrate the functionality of init-live.sh into new scriptlet named setup-live in order to support the live boot image. The udev-extraconf rdepends is being added to perform automounting. It gets to run before the rootfs and finish module.
The setup-live scriplet include the changes for:
- Create a conditional loop for the bootparam_root variable. If it is not set, then it will boot from ROOT_IMAGE. Else, it will boot normally which is not from removable media.
- Gives a standard path to the original boot disk mount which can be used to. While /media/sda is a good guess, it isn't always right, nor is it a good assumption that only one boot disk is in the system.
- The current rootfs module has no support for rootfs images, currently it only support for rootfs partitions for wic image. Therefore, there is a need to assign the rootfs image for live image.
