Hi,
I'm trying to build a ltsp-server as versatile as possible (old kernel
or not, fat or not...) because clients can be very different... We
have actually about 20 servers on Wheezy with NFS chroots with no fat.
At the moment, i install everything in a Jessie virtualbox... with the
script attached (thks Richard K and Vagrant C)
And i have many questions
- NBD seems to be really stable. The only advantage of NFS seems to
be able to modify chroot in real time... What do you think ?
- I can't login in gnome flashback when the client is not fat...
Apparently because there is no 3D acceleration... What can I do ?
- In my virtualbox, i can't try ltsp-pnp ... ltsp-update-image
--cleanup / remain stuck. Is it possible to have an ltsp-pnp in a
virtual machine (will surely be a kvm) ?
- Can ltsp-pnp have many kernels ? 586, 686-pae and amd64 ?
Thanks for your advices,
Nico
The script i use...

#1 install packages (if ltsp-pnp install ltsp-client on the server)
