initramfs-framework: module to support boot live image
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.
