Ubuntu 9.10 LTSP chroot not used
Hi All,

I setup Ubuntu 9.10 Desktop / ltsp 5.1.90-0ubuntu3, and using a Thin Client from (LTSP Term 1520 - PXE Boot - Thin Client<>)

After LTSP install following the docs on the thin client booted with no tweaking to any of the configs. While I can boot and login just fine it does not work as I expected.

1. When logged in as a regular user through the thin client I am not put into the chroot enviroment /opt/ltsp/i386 , the regular user can browse the real / directory. The only place I see that makes reference to chrooted environment is the /etc/ltsp/dhcpd.conf and /opt/ltsp/i386/etc/ltsp_chroot, which is as follows:




# Default LTSP dhcpd.conf config file.


subnet netmask {
option domain-name "";
option domain-name-servers;
option broadcast-address;
option routers;
# next-server;
# get-lease-hostnames true;
option subnet-mask;
option root-path "/opt/ltsp/i386";
if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
filename "/ltsp/i386/pxelinux.0";
} else {
filename "/ltsp/i386/nbi.img";

It looks to be set correctly... Ideas?

2. Also, the main config lts.conf has no entries what so ever, is that because the LTSP Thin Client work out of the box?

3. Also the lts.conf has a note that the lts.conf file should be located in /var/lib/tftpboot/ltsp/i386, the file did not exist there, so I'm guessing if you needed to use lts.conf you would create it there?

Any Help Greatly Appreciated.
