overlayfs, unknown filesystem type

jgmb45

Hello,

I'm running on ubuntu 14.04 and get "unknown filesystem type" when I try to use overlayfs.

Any hints to get this working? Doing a search this seems like it should work out of the box.

I don't see overlayfs registered in /proc/filesystems.

Here is what I'm doing:

sudo apt-get install update

sudo apt-get install initramfs-tools

sudo apt-get install overlayroot

cd /tmp

mkdir upper

mkdir lower

mkdir overlay

sudo mount -t overlayfs -o lowerdir=/tmp/lower,upperdir=/tmp/upper none /tmp/overlay

mount: unknown filesystem type 'overlayfs'
