ltsp-update-image bug with overlayfs issue

[EmmanuelLeNormand]

Hello
I would install ltsp-server and ltsp-client on ubuntu 15.04 for making ltsp-pnp server.
But the ltsp-update-image script have a issue when I use it :
root@phi-srv-gree:~# ltsp-update-image -c /
mount: wrong fs type, bad option, bad superblock on overlayfs,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.
Could not mount /tmp/tmp.nScQr2AHlR/amd64.

I searched and I saw in the old installation LTSP-PNP server the overlay module is up with this name: overlayfs
On the new installation, the module is up with this name : overlay
So, this module have some alias ; overlay, overlayfs... but the options are different.
I tested the new ltsp-update-image script in the dev-branch of ltsp code.
The image creation for LTSP-PNP start .
Bye
Manu

LTSP in Ubuntu is broken, use the Greek schools PPA like the ltsp-pnp page says.
The bug is fixed there.
