unless you manually configured NBD, Debian LTSP defaults to using NFS.
i wonder if running ltsp-update-image somehow sets the default to switch to
NBD? reading it quickly, i don't see where it would. running ltsp-update-image
is completely unnecessary with NFS based setups such as Debian, but a lot of
documentation suggests running it.

it surprises me that they wouldn't boot at all in that case...

it happens in the initramfs:
/opt/ltsp/i386/usr/share/initramfs-tools/scripts/nfs-bottom/ltsp
it is controlled by the HOSTNAME* parameters in lts.conf:
apt-get install ltsp-docs ; man lts.conf
for a network with ip addresses ranging from 192.168.0.1-192.168.0.254 (i.e.
netmask of 255.255.255.0), you'd get ltsp1-ltsp254 for auto-generated
hostnames... so a simple for loop could add them to your server's /etc/hosts:
for x in $(seq 1 254) ; do
echo 192.168.0."$x" ltsp"$x" >> /etc/hosts
done
or just set up DNS. as time has moved on, and we've configured more and more
workarounds, i'm wondering why we've avoided configuring DNS for LTSP
environments. i guess it's just one more service to have to configure...

Virtualization is moving to the mainstream and overtaking non-virtualized
environment for deploying applications. Does it make network security
easier or more difficult to achieve? Read this whitepaper to separate the
two and get a better understanding.
