Public bug reported:
Binary package hint: ltsp-server

Ubuntu 8.04 "Hardy"
ltsp-server:
Installed: 5.0.40~bzr20080212-0ubuntu7

If you create additional builds of the client, with this:
ltsp-build-client --base /opt/ltsp-test
Then change the dhcp server entry, so that the Root-path is:
/opt/ltsp-test
Then run this:
ltsp-update-kernels
The client should boot and pick up the small pxelinux, then swapping out
the 4Mb initrd for the NBD image as the '/' of the filesystem. It should
mount the NBD image in /opt/ltsp-test. It ends up mounting the default
one in /opt/ltsp, instead of the new one in /opt/ltsp-test.
I have tried to look into why this is, and I have found the file in the
initrd.img that contains the instructions as to which NBD to mount:
If you:
mkdir /tmp/pxelinux-initrd
cd /tmp/pxelinux-initrd
zcat /var/lib/tftpboot/ltsp/i386/initrd.img | cpio -i
This extracts the initrd that is mounted for pxelinux to use, during the
PXEboot process. In here is:
scripts/ltsp_nbd
This file looks to the variable 'nbdroot' to get the ipaddress and port number
to mount the NBD image from. This variable is not being set correctly. when
an alternative client build is created. The DHCP server is specifying
/opt/ltsp-test to show that a different image needs to be used. This does not
seem to be picked up to get the system to mount the alternative NBD image.
The ltsp_nbd script defaults to port 2000. It is possible to specify a
different NBD server and port, as arguments to the kernel in the
pxelinux.cfg, using the nbdroot=<server-ip>:<port> But this means
configuration needs to be done in two places. It should only need to be
done once, when the ltsp-build-client --base <directory> is issued.
I may be completely missing something, and not understanding how this
works.

-
- The ltsp-build-client sets up the pxelinux for the default client, but
- not for any subsequent ones
--
ltsp-update-kernels does not create separate pxelinux directory in
/var/lib/tftpboot for a client in a non-default location
