For cpio/ramfs the kernel will first attempt to execute /init and will
emit the following error as the file is empty:
Failed to execute /init (error -13)
If /sbin/init exists symlink to it so the kernel can immediately start
the correct init executable instead of an empty file.

If the first command returns an error, it will not cause the image generation
step to fail. Simply split up the statement into multiple lines to avoid
this issue, they no longer need to be one line expressions.

The Linux kernel requires that initrd images contain a /init file for
the image to be used as an initrd, even if it is empty. Adding it into
the rootfs directory creates a race, that can upset tar when building
both a .tar and .cpio image file ("tar: .: file changed as we read it").
Additionally, whether or not the tar file will contain the /init file is
also up to the race condition.
To avoid this problem, move the /init addition out from the rootfs
directory, and thus only include it in the .cpio image.

The image not correctly created if 'ptest-pkgs' is in IMAGE_FEATURES,
this is because there is no free inode left. We can use 4096 instead of
8192 bytes-per-inode to fix the problem, and most of the distributions
us 4096, such as Ubuntu, Suse, Fedora and CentOS.
There are another problems:
* There are error message when there is no free inode left if we run the
mke2fs command manually, but they are not in log.do_rootfs.
* The image generation doesn't stop when error happens because mke2fs
doesn't return failed for this case.
Will fix them in other threads.

We used populate-extfs.sh which invoked the debugfs to create the image,
now the mke2fs' option "-d root-directory" can do the same thing, and
which is more faster, for example, the core-imag-sato:
* In the past:
$ time mke2fs -t ext4 rootfs.ext4
real 0m0.249s
user 0m0.036s
sys 0m0.132s
$ time populate-extfs.sh /path/to/rootfs/ rootfs.ext4
real 0m29.355s
user 0m10.637s
sys 0m5.544s
* Now:
$ time mkfs.ext4 -F -d /path/to/rootfs/ rootfs.ext4
real 0m6.338s
user 0m3.824s
sys 0m1.356s
More than 25 seconds are saved.

The following dependencies were manually added in the image creation
code. However, in order to have an image dependency mechanism in place,
use a new variable, IMAGE_TYPEDEP, to declare that an image type depends
on another being already created.
The following dependencies are added by this commit:
elf -> cpio.gz
live -> ext3
vmdk -> ext3
iso -> ext3
hddimg -> ext3
This commit adds also another new variable: IMAGE_TYPES_MASKED. Currently,
masking out certain types from IMAGE_FSTYPES was hardcoded in the image
creation code.

lib/oe/image.py: fix working directory
The working directory needs to be changed before the image creation
commands instead of afterwards.
exposed an issue when generating tar images, where it would cd into
rootfs and then create the rootfs tarball and remain there since the
cmd to cd into deploy dir moved up the immediate following cmd like
tar.bz2 or tar.gz were still looking for tarball in current directory
which esentially was not deploy dir but IMAGE_ROOTFS instead

I got hit by a missing dependency in generation of sum.jffs2 images - at
runtime, when images are generated using bitbake pool, it is possible
for sum.jffs2 image to be scheduled for generation before jffs2 image is
fully generated.
Insted of adding additional hacks, reimplement sum.jffs2 generation as a
compression scheme on top of plain jffs2 images. For now support for
sum.jffs2 images is left in, it will be removed by the subsequent
commit.

We're seeing a pattern of one image type needing to depend on another
type. A good example is jffs2 and sum.jffs2. This patch makes sum.jffs2
depend on jffs2 which will then allow a EXTRA_IMGAGECMD to be set for
sum.jffs2 individually without changing the jffs2 command. This allows the
-pad option to be configured differently.

For mkfs.jffs2 endianness can be be expressed in the long or short form
with the optional size argument:
--little-endian
-l
Strangely the sumtool has a different syntax and does accept the forms:
--littleendian
-l
Prefer the short form valid for both tools.

* The benefits:
- Really support ext4
- Support the sparse file (we lost the sparse file in the image in the
past, the sparse file became into the common file)
- Fix the error reported by fsck: (ext2/ext3)
Inode 1025, i_size is 16384, should be 17408.
- Have a uniform code for ext2/3/4 generation
* Comments from Darren Hart:
Basically, genext2fs doesn't support creating ext4 filesystems. It
creates, as I understand it, an ext2 filesystem, then adds a journal,
and sets some bits. It can't support the newer features like extents. So
what we end up with is a bit of a hack for a filesystem.
The ext tools (e2fsprogs) unfortunately don't provide an integrated
solution for generating prepopulated filesystem images as many other
mkfs* tools do. One thing missing was symlink support in libext2fs. I
added that support and demonstrated a script which uses the e2fsprogs
debugfs tool that can populate the newly formatted filesystem from a
directory and without root privileges.

Generating filesystems with this flag allows more efficient directory
traversals because getdents() returns the filetype in 'd_type' which
allows to avoid an extra lstat() call.
Creating ext4 filesystems with 'mkfs.ext4' sets this flag by default
too.

error: "Filesystem uses "lzma" compression. This is not supported".
Currently (well at least in Linux 3.8) the officially supported

* XZ
* ZLIB

If we round up ROOTFS_SIZE to IMAGE_ROOTFS_ALIGNMENT before checking if
base_size is greater then IMAGE_ROOTFS_SIZE, we can end up adding an
unaligned value to IMAGE_ROOTFS_SIZE. Obviously, if
IMAGE_ROOTFS_EXTRA_SPACE was overwritten with an unaligned value. So
let's add the round up code after the base_size calculus and it's
comparison.
