There's no reason to have that rootfs.img filesystem in the image:
it's not used for anything because both the EFI and legacy boot paths
use the /initrd which contains the same contents as the rootfs.img,
only compressed. It was probably forgotten in there :)
My iso went down from 224 to 94 mb.
Tested using UEFI/legacy boots on CD-roms, usb dongle and qemu VM's.

It's really good that OE supports multiple EFI_PROVIDERs and that
commit 9a1709278de87 ("wic: isoimage-isohybrid: use grub-efi from
deploy dir") makes re-use of the grub-efi built image, but we should
still respect the standard otherwise the ISO will not boot, so install
grub images as boot[x64|ia32].efi not ${PN}-boot[x64|ia32].efi.

isoimage-isohybrid plugin tries to build grub-efi in its working
directory if it can't find efi binary. Wic should avoid doing anything
in working directories of other recipes. It should use artifacts from
the image deployment directory instead.

isoimage-isohybrid plugin uses result of glob call to
get path to initrd image. When glob returns empty list
the plugin crashes with IndexError.
Checking if result of glob call is not empty should fix
the breakage.

At the moment, when building images with IMAGE_FSTYPES=wic one ends up
depending on wic-tools and thus syslinux and grub-efi even when not
using those at all. Ideally, building an image with wic should only
build the tools and components really needed.
The problem is that "wic-tools" is needed also for the manual
invocations of wic, in which case everything that might be needed has to
be built in advance.
Replaced dependency on wic-tools with dependency to a much shorter set
of tools that wic uses almost for any image: 'parted', 'gptfdisk',
'dosfstools' and 'mtools'.

isoimage-isohybrid plugin fails with this error when
trying to find initrd image:
initrd = glob.glob('%s/%s*%s.%s' % (initrd_dir, image_name, target_arch, image_type))[0]
IndexError: list index out of range
as it uses TRANSLATED_TARGET_ARCH value as part of the image.
This approach stopped to work due to changes in oe core code.
initrd file name is made using MACHINE variable. wic can't get value
of this variable as it's not included into bitbake -e output.
Used basename of deploy dir as MACHINE value to fix the breakage.

Disk operations were spread over DirectPlugin, DiskImage and Image
code making the code hard to understand.
Renamed Image class to PartitionedImage.
Removed DiskImage class.
Moved disk operations to PartitionedImage.
There was an implicit support for multiple disks: if different devices
were specified in .wks file (e.g. --ondisk sda and --ondisk sdb), wic
would theoretically generate multiple images. This is quite confusing
option and the code supporting it was broken for a long time. The same
effect (multiple output images) can be achieved in obvious and clear
way - by using multiple .wks files.
This functionality was removed. PartitionedImage works only with
one image. This makes the code less complex and easier to maintain.

isoimage-sihybrid plugin uses MACHINE_ARCH to get the name of initrd image.
It doesn't work for all machines, for example for quemux86-64 machine
MACHINE_ARCH is quemux86_64 and initrd name is
core-image-minimal-initramfs-qemux86-64.cpio.gz

The purpouse of this function was to check dependencies for building a
hybrid iso and build them using bitbake if not found. Calling bitbake in
this context means this wic plugin itself cannot be instrumented inside
bitbake recipes which is undesirable, the benefits of this are clear:
there is no need to maintain outside scripts to generate an iso using wic
and the isohybrid building logic can be further abstracted away into an
isohybrid.bbclass in the future which can be easily inherited or something
similar.
So remove the function and add all dependencies to NATIVE_RECIPES so that
wic can print useful errors when they're not built.
To automate building the isohybrid image dependencies, add the following
somewhere in your image build inheritence hierarcy (or maybe create a
bbclass in the future to do these sort of things automatically):
DEPENDS += "syslinux syslinux-native cdrtools-native e2fsprogs-native \
parted-native dosfstools-native mtools-native grub-efi-native"

The latest wic kickstart refactoring introduced a bootloader option
"--configfile" which lets wks' specify a custom grub.cfg for use
while booting. This is very useful for creating stuff like boot menus.
This change lets isoimage-isohybrid use --configfile; if this option is
not specified in a wks, it generates a default cfg as before.

Take `pwd` to be <initial-dir>. The %s path is relative to it. The value
of %s is "output_folder/build". The current code works as follows:
Changing directory to %s and finding the sources (after cd'ing) to cpio
with output redirection to %s/initrd.cpio triggers the following error
"Error: exec_cmd: cd output_folder/build/INITRD && find . | cpio -o -H
newc >output_folder/build/initrd.cpio returned '1' instead of 0"
This happens because after the cd, `pwd` is <initial-dir>/%s and by the
redirect we write the result to to <initial-dir>/%s/%s/initrd.cpio which
obviously does not exist.
Fix this by getting the sources with "find %s" instead of "cd && find ."

This plugin creates a hybrid, legacy and EFI bootable ISO image.
The generated image can be used on optical media as well as
USB media.
Legacy boot uses syslinux and EFI boot uses grub or gummiboot (not
implemented yet) as bootloader. The plugin creates the directories
required by bootloaders and populates them by creating and
configuring the bootloader files.
The plugin adds an image file to the iso which
contains the directory tree of the rootfs folder specified by the
--rootfs argument or by the IMAGE_ROOTFS bitbake variable.
Using the isohybryd tool, the created .iso image is enhanced by a MBR
for booting from disk storage devices, consequently the provided
iso image could be copyed directly by dd comand onto USB drive or
could be burned to an optical media by using a suitable image burner.
The plugin depends on parted, e2fstools, syslinux, grub, cdrtools,
dosfstools and mtools program.
Some of the functions in this plugin were inspired from bootimg-efi.py
and bootimg-pcbios.py plugins implemented by Tom Zanussi.
