I wasn't able to install to my Optane SSD due to the following error:
Formatting /dev/nvme0n1p1 to vfat...
mkfs.fat 4.1 (2017-01-24)
mkfs.vfat: unable to open /dev/nvme0n1p1: No such file or directory
Target install-efi failed
A couple lines later I see:
[ 10.265401] nvme0n1: p1 p2 p3
Then looking at the device itself after booting from a USB stick:
root@intel-corei7-64: ~# ls /dev/nvme0n1*
/dev/nvme0n1 /dev/nvme0n1p1 /dev/nvme0n1p2 /dev/nvme0n1p3
So it looks like the parted commands return before the device node is
actually created.
Work around this issue by waiting for device nodes for a short duration.

When systemd is used, it will invoke a service on first boot that triggers
a rebuild of ldconfig caches (rebuild dynamic linker cache).
This is fine on the first boot of a system that has been installed, but it
makes no sense on a live system. The worst part is that rebuilding this
caches is slow and it causes the live system to take longer to boot.
(I measured this in 30 seconds longer on a standard PC system booting
core-image-sato live from an USB memory).
Disable this by touching /etc/.updated and /var/.updated on the live initramfs.

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.

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.

The init-install.sh and init-install-efi.sh scripts perform a check
to see which devices are available on a booted system for installation.
Recently, the way we check for these devices changed on 993bfb,
greping for devices found on /sys/block/, this change caused the installer
to fail (at least) when not finding any mmcblk devices, due to the fact
that we call sh -e to execute this script, so any command (grep)
or pipeline exiting with a non-zero status causes the whole script to exit
This patch throws in a harmless true exit status at the end of the pipeline(s)
of the grep commands to avoid the installer script from exiting, fixing the issue.

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).

That's because the actual error, not being able to find the root

Promoting the "root '$bootparam_root' doesn't exist." message from

The base-files recipe installs /mnt/mtab (it is a softlink of /proc/mounts),
so if an image includes the latter, there is no new to created it again inside
the install-efi.sh script, otherwise an error may occur as indicated on the
bug's site.

When the init_fatal_sh boot parameter is present (i.e. used without
value) and a fatal problem occurs inside the initramfs-module, a shell
will be started instead of looping forever.
Useful for debugging.
Interestingly enough, the code was already indented to support such an
if check...

It can be useful for debugging to override the default /sbin/init.
This is something typically done via the init boot parameter which
then gets interpreted by the kernel. But when using an initramfs, it
is the initramfs which must react to the option.

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
initramfs-framework's boot param support.

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()])}"

Kernel parameters like "uvesafb.mode_option=640x480-32" were turned
into shell variables named "bootparam_uvesafb.mode_option", which
triggered errors from the shell because the name is not valid. Now
points get replaced with underscores, leading to
bootparam_uvesafb_mode_option in this example.

Some kernels, for example linux-yocto 3.19 for qemux86, fail to
execute /init in an initramfs unless there is already a /dev/console
char device in the initramfs. Booting then fails with:
Kernel panic - not syncing: /dev/console is missing or not a character device!
Please ensure your rootfs is properly configured
The panic itself comes from a linux-yocto specific patch to
kernel_init_freeable in init/main.c, but even without it, that
function will print an error when /dev/console is missing. The
kernel's Documentation/initrd.txt also mentions creating that device.
It remained unclear why this is not a problem on other machines. On
intel-corei7-64 from meta-intel, something (the kernel?) creates
/dev/console and /dev/[012] before transfering control to the init
script. In that case, creating /dev/console in advance is not
necessary, but does not cause any problem either.
