rootfs contains config and metadata from the kernel used when bootstraping the rootfs

[Ricardo Salveti]

This with both 15.04 and rolling:

The config can be quite confusing, since it can give the idea that this is the config used for the running kernel, which is not true :-)

Setting to critical because its a) confusing b) easy to fix in the livecd-rootfs code.
