[YOCTO #1487]
For the liveCD image, interactive bootup is needed, but psplash prevents from
booting interactively. In such case ISO image is not usable, so remove ISO image
and the corresponding link and throw error info to warn outside to enable
unionfs in kenrel.
I'm just bumping Yang's review. I worked with him on this problem
(which turned out to harder than we initially thought).
Does anyone else have better suggestions than this ? This keeps the
live image bootable and interactive when X is in play, but it has
some obvious side effects.
Cheers,
Bruce
