Yes they are constant from the client point of view. But they may be
modified on the server.

This is a complete filesystem, in this filesystem there is a full FHS
tree.

It is generated. Plan is more or less to install rpms in the direrctory
like a chroot.

The plan is to install it as a rpm chroot, but it will also be
configurated, with a file in the *ltsp5/i386/etc/ltsp.conf or the like
holding information for all the hosts using this root filesystem.

It is an arch dependent chroot (depending on the terminal hardware), 
so there will be 
*/ltsp5/i386
*/ltsp5/ppc
....

It is a full filesystem with its own /etc, /usr/share and so on and so
forth. It is more similar with mock chroots in my opinion. With the
difference that these chroots are to be NFS exported.

It may hold the swap partition of the terminal, nbd is the protocol
used to transparently use it from the terminal, although it is on
another host (NBD is Network Block Device).
