If you want swap over NFS then make a Debian kernel package with support
for swap over NFS. It is not provided officially in Debian because it is
considered too rarely needed for the maintainance burden of an extra
kernel with the unofficial patch applied.
So if you consider it a plus that LTSP has a custom-patched kernel then
I recommend you to use a kernel deriving as little as possible from the
official Debian ones, and rebuildable with same routines as the Debian
kernels, instead of relying on an alien distribution for some of the
Linux kernels in your network.

...and that off course will be even better when it works, because then
we need only the NBD module unofficially compiled, not a complete kernel.
But the old-fashioned approach of LTSP is possible with Lessdisks as
well, if that is what you want. And much easier to maintain.

Yes. Off course!
Why would I *not* want Lessdisks officially upgraded to a newer version?

...which is why the official Lessdisks is currently stalled.
Preferrably I want an upgrade path to be found from current official (in
Debian!) package to whatever is chosen to be let in as next official
release, but most importantly I want _next_ release to be upgradeable
(which I believe is not yet properly ensured upstream).
So yes, I want lessdisks upgraded for Debian, but not at all cost.
