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.
For the liveCD image, interactive bootup is needed, but psplash prevents from
booting interactively. In such case ISO image is not usable, so throw warning
info when building ISO image without unionfs enabled in kernel.
We tried a lot of different ways to achieve this:
1. Check if ISO image is built in initramfs-live-boot.bb or not, then prevent
from generating ISO image.
But, we can't distinguish minimal image or sato image.
2. Check if x11 feature is included in initramfs-live-boot.bb or not, then
prevent from generating ISO image.
But, x11 feature is contained in minimal image as well even though the package
is not built.
3. Tried to append some check code in build_iso() in core-image-sato.bb, but
poky can't support append code
in build_xxx functions like what we do for do_xxx funcitons.
So, we came up with current solution. Any new suggestion is appreciated.
One more thing is that if IMAGE_FSTYPE += "live" is not set in conf/local.conf
with this fix, we will get below
error when building sato image:

Bruce pointed out there was a large discussion about this on hte list last
week, so this should be a known issue in poky.
I am not finding the discussion, maybe it's under some other title, can
someone please point me at this large discussion about the above failure?
The following changes since commit f81b0593e74a31cb2d992df0583948ff57e3ed98:
gdbm: Activate -enable-libgdbm-compat and add symlinks to headers in
include/gdbm (2012-03-23 17:56:29 +0200)

Yang Shi (2):
initrdscripts: fix init-live.sh and use unionfs
merged this one in
sato: Throw warning when building ISO image without unionfs enabled
This is not merged since in the normal case with out live in
IMAGE_FSTYPES, the above error occurs, that is not the proper way to
handle this.
The underlying issue needs to be addressed first.
