OK, still trying to clarify this...

I create a fat-client chroot that has a bunch of stuff in it. In
particular, in my lab I teach programming, so I've got a few
programming languages installed, Google Chrome, etc. Then I run
ltsp-update-kernels, ltsp-update-image, and ltsp-update-sshkeys, just
to make sure everything got updated.

Now, does the fat-client download *everything* in the chroot into RAM,
or does it mount the chroot remotely and only download what it needs
to boot, loading the other stuff from (the server's) disk as it needs
it? I guess what I'm asking is, is the part that the client gets over
the network to boot considerably more for a fat-client than a
thin-client, or is it about the same, with the fat-client then
mounting the files it needs on the server?
