Auto-calculation of the rootfs size cannot be done in a reliable way
as it depends on the host filesystem and is broken on non ext4 host
(see bugs [1] [2]). So let the user specify the size he wants for his

The iso9660 generation for grub2 assumes that grub-eltorito.img is
available. However, this image is only available for the i386-pc target
(i.e. legacy BIOS). An EFI-bootable iso9660 requires a different layout.
Since we currently can't generate the EFI-bootable iso9660 layout,
require the i386-pc target to be selected in grub.

Currently, when there is no syztem device table (permissions or static
devices) defined, then package permissions are not applied, because they
are guarded by the check on the system device tables being non empty.
Fix that by narrowing the guarding condition.
Note that the dependency on host-makedevs was not conditional; we always
build it even if we don't need it. Making it conditional is not
possible, because we don't know all the packages permissions by the time
the fs infra is parsed (packages from br2-external are parsed after it).

The Advanced XIP File System is a Linux kernel filesystem driver that
enables files to be executed directly from flash or ROM memory rather
than being copied into RAM. It has the ability to store individual
*pages* in a file uncompressed/XIP or compressed/Demand Paged.
This commit only adds support for 'XIP all' mode, so all the files that
have the execute attribute set will be XIP'ed.
At the moment, the FS is not supported in Linux mainline (v4.3-rc5), so
the kernel has to be built with the axfs patches to be able to read it.

forget to build host-mkpasswd, leading to build failures if you don't

Until now, the iso9660 filesystem handling only supported using an
initrd/initramfs to store the root filesystem, which is very different
from what we do with the other filesystems.
This commit changes the iso9660 logic to also allow using directly an
iso9660 filesystem to store the root filesystem. A new option,
BR2_TARGET_ROOTFS_ISO9660_INITRD, is created to tell the iso9660 that
we want to use an initrd and not directly the root filesystem in
iso9660 format. This option defaults to 'y' to preserve the existing
behavior.
After this commit, we therefore have three possibilities:
* BR2_TARGET_ROOTFS_ISO9660=y, with BR2_TARGET_ROOTFS_INITRAMFS and
BR2_TARGET_ROOTFS_ISO9660_INITRD disabled. In this case, the
iso9660 filesystem is directly the contents of the root filesystem
(since is possible thanks to the Rockridge extensions that were
already enabled using the -R option of genisoimage). Obviously, it
means that the root filesystem is read-only.
* BR2_TARGET_ROOTFS_ISO9660=y and BR2_TARGET_ROOTFS_INITRAMFS=y (the
value of BR2_TARGET_ROOTFS_ISO9660_INITRD doesn't matter). In this
case, the root filesystem is already linked into the kernel image
itself, as an initramfs. So the iso9660 filesystem doesn't contain
the root filesystem as is, but just the bootloader and the kernel
image.
* BR2_TARGET_ROOTFS_ISO9660=y, BR2_TARGET_ROOTFS_ISO9660_INITRD=y and
BR2_TARGET_ROOTFS_INITRAMFS disabled. In this case, a separate
initrd is used. The iso9660 filesystem only contains the
bootloader, the kernel and the initrd.
In order to support the first case out of the box, root=/dev/sr0 is
added on the kernel command line in the example Grub configuration
file, so that the kernel knows where the root filesystem is
located. This argument is ignored when initrd/initramfs are used.

The iso9660.mk modifies the menu.lst file from Grub to set the correct
initrd/kernel image locations. However, with the upcoming support of
other bootloaders for iso9660 filesystems, we need to modify a bit
this logic.
Instead of relying on the specific details of the grub menu.lst
syntax, we introduce the __KERNEL_PATH__ and __INITRD_PATH__ magic
keywords, which iso9660.mk will replace by the appropriate
values. They can therefore be used where needed in grub menu.lst, and
in similar configuration files of other bootloaders, as will be
supported in the following commits.
Also, in order to be consistent with the soon to be introduced support
for having the root filesystem itself as iso9660, this commit changes
the installation location of the initrd and kernel. Instead of being
/initrd and /kernel, they become /boot/initrd and
/boot/$(LINUX_IMAGE_NAME).
