[yocto] Make one directory writeable

[Ulf Samuelsson]

You can use overlayfs for this. You mount the overlayfs on top of your rootfs and then it appear like you have a writeable file system.
In reality all the new  stuff is written to another (writeable) file system.
If you dismount the overlayfs, the rootfs reverts back to its original state.
If you again  mount the overlayfs, you get your modifications back.
