f13f1dd286 initramfs-framework/udev: call settle before kill
When mount command is executed in rootfs module of initrd, eudev creates
a loop0 device node, applies rules and adds a inotify watch to it. Right
after this step, we execute finish which first tries to kill any running
udevd daemon before doing a switch_root.

In some cases, it is possible that switch_root is executed before
inotify_add_watch was actually processed which would lead to errors like:

| inotify_add_watch(6, /dev/loop0, 10) failed: No such file or directory

Make sure that we process all the events in queue before actually trying
to kill udevd to prevent this race.

769c774f89 initramfs-framework/setup-live: also boot live image if root=/dev/ram0
Our grub and syslinux bootloaders both define root=/dev/ram0 for live
images by default. Kernel docs show that root=/dev/ram0 is just a
sentinel value for the kernel to mount the initrd as root, which then
mounts and switches to the real root. This is exactly what our scripts
do, so just check for root=/dev/ram0 as well.

See: https://www.kernel.org/doc/html/v4.11/admin-guide/initrd.html#operation

This fixes the issue where the new initramfs-framework scripts would not
boot live images that use grub or syslinux bootloaders.

716d5d9e65 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.

ee6a6c3461 initramfs-framework: add retry loop for slow boot devices (like USB)
On some hardware platforms (Gigabyte, qemu), detection of USB devices
by the kernel is slow enough such that it happens only after the first
attempt to mount the rootfs. We need to keep trying for a while
(default: 5s seconds, controlled by roottimeout=<seconds>) and sleep
between each attempt (default: one second, rootdelay=<seconds>).

This change intentionally splits finding the rootfs (in the new
"rootfs") and switching to it ("finish"). That is needed to keep udev
running while waiting for the rootfs, because it shuts down before
"finish" starts. It is also the direction that was discussed on the OE
mailing list for future changes to initramfs-framework (like
supporting a "live CD" module, which would replace or further augment
mounting of the rootfs).

d6e40e80d1 initramfs-framework: better error reporting for invalid root boot parameter
When the "boot" parameter refers to a non-existent device, the only
visible output at normal log levels was a rather confusing:
   ERROR: There's no '/dev' on rootfs.

That's because the actual error, not being able to find the root
device, was only a debug message, which gets ignored in the default
mode.

Promoting the "root '$bootparam_root' doesn't exist." message from
"debug" to "msg" gives sufficient context to understand the error. A
more intrusive change would be to change also the control flow.

Default is to mount the rootfs read/write. "ro" can be used to turn
that into read-only, which is useful on systems where userspace does
an fsck before remounting read-write.

Giving both "ro" and "rw" will still mount read-only regardless of the
order, because the ordering information is not preserved by the

d7508fee30 initramfs-framework: support rootflags and rootfstype boot parameter
These two parameters are supported by the kernel
(https://www.kernel.org/doc/Documentation/kernel-parameters.txt). When
an initramfs is used, the kernel does not mount the rootfs and the
initramfs needs to react to them.

The boot parameters can be set both by the image creator and
by users.

Supporting these two parameters is useful:
- rootflags is needed to ensure that the rootfs is already mounted as
  intended in the time between starting init and init remounting
  it (as systemd does); this is critical for IMA where iversion must be
  active already when system starts writing files.
- setting it correctly up-front avoids messages from the kernel ("cannot
  mount ... as ext2 because ...") when trying to guess the desired type.

For example, assuming that only one of ext4/ext3/ext2 is set,
rootfstype could be set in an image recipe with:
APPEND_append = "${@''.join([' rootfstype=' + i for i in ['ext4', 'ext3', 'ext2'] if i in d.getVar('IMAGE_FSTYPES', True).split()])}"
