Symlink i386 -> amd64:
sudo ln -s amd64 /var/lib/tftpboot/ltsp/i386

Check/send output of this command:

LTSP is fine in 14.04, and ltsp-pnp is fine too. No problem there.

Network-manager/dnsmasq has an issue, it needs "bind-interfaces" changed
to "bind-dynamic" in /etc/dnsmasq.d/network-manager.

If you're using gnome-flashback, it's a bit more unstable in 14.04 vs
what it was in 12.04.

Also for people that have ancient clients (10-15 years old), the new
xorg in 14.04 doesn't support graphics cards that use XAA, like s3.

So here I adviced schools to stick with 12.04.
