ad42d8e4d9 isoimage-isohybrid: don't include cpio in cpio image
Because the find | cpio processes execute in parallel connected via
the pipe, and the cpio outputs in the same dir find searches for
source files, the cpio will be included in itself partially, depending
on how fast the build machine creates the cpio file before cpio
gobbles it up.

This bloats the ISO image, though compression reduces the .iso file size,
once the kernel decompresses the cpio image and boots it live, it uses
up to double the RAM memory.

Fix this by creating the initrd.cpio file directly inside cr_workdir.

0dc9785c08 isoimage-isohybrid: Fix variable names
initrd.cpio is created in initrd_dir, not in cr_workdir. Gzip will
let initrd.cpio uncompressed if the path is not found.

Also, grub_image variable doesn't exist, grub_src_image should
be used instead.

87943f2fe0 isoimage-isohybrid: Fix creating initrd.cpio
Only bsdcpio works with numbers for option -R to specify user:group,
while GNU cpio doesn't. Debian use GNU cpio so without this change,
you cannot create ISO images without installing bsdcpio.

870fbbd5c0 wic: isoimage-isohybrid: debloat image of redundant rootfs
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.

b591fb889b wic: isoimage-isohybrid: fix UEFI spec breakage
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.

b6dd87f2a8 wic: get rid of using wic-tools
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'.

684534198f isoimage-isohybrid: don't use TRANSLATED_TARGET_ARCH
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.

adf5e2956c wic: move disk operations to PartitionImage class
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.

436df4de37 wic/isoimage-isohybrid: remove do_stage_partition()
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"

eb134c6ee6 isoimage-isohybrid.py: fix cpio working directory
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 ."

5cd222b19f wic: get rid of get_rootfs and set_rootfs
Got rid of get_rootfs and set_rootfs java-like getter and
setter. Renamed rootfs to rootfs_dir to be consistent with
the name of kickstart parameter --rootfs-dir.

4d5d5dd428 wic: get rid of get_timeout getter
Used bootloader.timeout instead of kickstart.get_timeout getter.

Accessing attributes instead of getting them with getters is
more pythonic, shorter and readable. It also more consistent as
most of partition and bootloader attributes are used this way.

This change also takes care of appendLine bootloader attribute:
it's renamed to bootloader.append attribute provided by new parser.

de5bc1b758 wic: Add plugin for hybrid iso image
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.
