no *need* to remove it, other that the relatively small amount of wasted disk
space and confusion of having it around.

i don't really see any clean way to do this, as with debian (and presumably
ubuntu) you can run NFS and NBD LTSP environments on the same server. there are
also options to use NBD without using ltsp-update-image, and running
ltsp-update-image will clobber it, and recent versions will rewrite a bunch of
configuration files for good measure.
there's no simple way to detect which of these scenarios is in use. i suppose i
could add a configuration file that causes ltsp-update-image to exit, and
explains how to change the behavior...
in short, if you don't want to switch to NBD, don't use ltsp-update-image. just
don't. ugh.
live well,
