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.

After removal of auto-creating S we must ensure that all recipes are
using a proper value for S.
Fix all recipes that only need to set S equals to WORKDIR.

There are cases where software after boot may need to know the
current boot disk. Under the current system, it is not guaranteed
which disk is the boot. 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. This gives a standard path to the original
boot disk mount which can be used to, for instance, update the
syslinux file on the boot media with a newer kernel, or updating
the boot parameters to add user options for future boots. Knowing
which disk is the boot media keeps from updating the non-boot
disk when for instance multiple syslinux boot medias are plugged in
(ie ensure correct syslinux is updated when the booted system is
updated).

A lot of our recipes had short one-line DESCRIPTION values and no
SUMMARY value set. In this case it's much better to just set SUMMARY
since DESCRIPTION is defaulted from SUMMARY anyway and then the SUMMARY
is at least useful. I also took the opportunity to fix up a lot of the
new SUMMARY values, making them concisely explain the function of the
recipe / package where possible.

The unionfs has been disabled for more than a year and it's not going
to be used any more.
This patch cleans up the unionfs related code.

init-live.sh depends on udev performing automounting, which happens in
udev-extraconf. Explicitly depend on it so that we always have it installed.

udevd moved location and isn't in $PATH anymore, so use an absolute path to
start it.
The control socket path moved too, so mkdir the directory it's in.

are resolved
There are issues with the current unionfs when making a union mount over "/".
Until these are resolved we can't use unionfs for live booting so disable this
temporarily as a workaround.
unionfs is usable in other circumstances.

[YOCTO #1487]
When booting up with liveCD image, init scripts can't work well on read-only filesystem. Unionfs,
which is supported in Yocto kernel, allows a filesystem to appear as writeable, but without
actually allowing writes to change the filesystem.
Use unionfs to mount rootfs and make root file system can be writen when using liveCD to boot up.
Set UNION_FS variable depending on kernel config, so that it can work with kernel which doesn't
have unionfs feature.

The script was making some assumptions that enforced many requirement
in the machine kernel configuration and usage, besides it were too
while booting.
Changes included:
* fix indentation;
* rdepends on udev;
* allow use of isofs as module;
* remove rootdelay param parsing as it was unused;
* don't verbosely kill udevd and mknod;
* mount devtmpfs into rootfs, if available, before swithing root;

If we don't set PATH, then the shell will specify one for us.
Busybox adds the sbin dirs, but bash does not. I hit an
issue where bash (among other things) ended up in my initrd
and the boot scripts failed due to a bad default PATH. While
that is a separate issue, we should not be at the mercy of the
shell's default PATH. Update the initrdscripts to all specify:
PATH=/sbin:/bin:/usr/sbin:/usr/bin

Both hddimg and livecd use init-live.sh script to boot the rootfs.img.
But the paths of rootfs.img in hddimg and livecd are different. So we add
a variable "ISOLINUX" to provide a correct path.

Fix bug: [YOCTO #686]
Because the variable "ROOT_IMAGE" in init-live.sh is not correct, it fails to
run when using liveCD. Modify value of "ROOT_IMAGE" to "isolinux/rootfs.img".
If we want to use liveCD, we also need to add some kernel options related to
CDROM support when compling kernel.

The existing PACKAGE_ARCH = "all" mechanism of sharing packages is problematic
with sstate since there are a variety of variables which have target specific
values and the sstate package therefore correctly changes signature depending
on the MACHINE setting.
This patch creates a new "allarch" class which sets:
PACKAGE_ARCH = "all"
(as per the existing convention)
INHIBIT_DEFAULT_DEPS = "1"
(since its not target specific and therefore can't depend on the cross
compiler or target libc)
TARGET_ARCH = "all"
TARGET_OS = "linux"
TARGET_CC_ARCH = "none"
(since these variables shouldn't change between the different packages and
target compiler flags shouldn't be getting used)
PACKAGE_EXTRA_ARCHS = ""
(since we shouldn't be depending on any architecture specific package architectures)
Not all PACKAGE_ARCH = "all" recipes can use this class since some run configure
checks on the compiler. This means they have target specific components and therefore
the "all" classification is incorrect.

Having one monolithic packages directory makes it hard to find things
and is generally overwhelming. This commit splits it into several
logical sections roughly based on function, recipes.txt gives more
information about the classifications used.
The opportunity is also used to switch from "packages" to "recipes"
as used in OpenEmbedded as the term "packages" can be confusing to
people and has many different meanings.
Not all recipes have been classified yet, this is just a first pass
at separating things out. Some packages are moved to meta-extras as
they're no longer actively used or maintained.
