Comment # 15 on bug 950999 from Takashi Iwai

Meanwhile, we can work around it by changing the fs type to another one, e.g.
ext4.  It's a storage for a live image, and the snapshot or other nice features
aren't so important.  It's often better just to have a lighter fs instead.

Coolo, could you modify the kiwi config.xml to specify the filesystem
attribute, if not done yet?
