Oh, I didn't know about local-port and remote-port: I'd been changing
the port in the init script.

/usr/share/initramfs-tools/scripts/ltsp_nbd
contains this:
if [ -n "$dhcpport" ]; then
DHCPPORT="$dhcpport"
fi
which makes me think there must be another way of setting the port.
I found this: https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/198356
which suggests that the port can be specified in the lts.conf file.
So I changed the port in /usr/share/initramfs-tools/conf.d/ltsp

Unfortunately the client still requests DHCP info on port 67.
I also tried adding the following after those lines in ltsp_nbd:
DHCPPORT="1068"
But the dhclient still requests on port 67.
I tried editing /usr/share/initramfs-tools/scripts/nfs (then
mkelfImage, and cp ...), but that didn't make any difference either.
The datestamp is updated and the file size of the nbi.img and
initrd.img files is changed, so mkelfImage does seem to be doing
something.
Steve, please let me know when you update your system. I've obviously
done something incorrectly.
Thank you,
Sean
