Not true .. overlayfs is one way to have a read/write ISO, but
not the only.

This isn't something we bury in the middle of the ktypes. aufs
has always been a standalone configuration option, and one that
is enabled via KERNEL_FEATURES.

This is an alternative to the exiting aufs use case, and should
be treated a similar way (with a generic feature, an enable and
a disable). See the aufs fragments as a template to follow.
