well, the default, i believe, is to actually use the same remote X11
technology as LTSP does by default: XDMCP (a.k.a. xdm/kdm/gdm). though
lessdisks also supports sdm, which uses ssh encrypted sessions (which is
merely a few simple wrappers using ssh and Xdialog).

lessdisks ran for over two years at freegeek using XDMCP, before sdm
existed.  i've personally experimented a little using VNC.

if you can get it to work for a conventional debian workstation, it's
likely able to work with lessdisks, many things without alteration.

and lessdisks is getting easier all the time, i'd like to think :)

the newer upstream versions (0.6.x) has a number of features to make
install significantly easier, including more flexible commandline
options at chroot install time, debconf pre-seeding (both for the server
and chrooted packages), installs from file:/// archives, support for
multiple chroots and even man pages!

i hope to have an update release in the near future with updated
documentation and some tweaks jonas made with argument processing.

you can also use lessdisks to create livecds or read-only root disked
systems, though it requires much more manual tweaking currently.

you could even run lessdisks terminal servers that are themselves
"diskless" terminals :)

i have dreams of being able to support networked root filesystems other
than NFS someday, such as OpenAFS, GFS or who knows what else- the basic
framework to make some of that is possible using an initrd and
initrd-netboot-tools. just needs someone familiar with the particular
network FS technology and the client-side tools needed to mount it.

enough shameless plugs, hopefully debian-edu will find some use in
lessdisks :)

live well,
