Subject: [PATCH 2/2] sato: Throw warning when building ISO image without unionfs enabled
Precedence: list
Content-Type: text/plain

[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 throw warning
info when building ISO image without unionfs enabled in kernel.
