After installing LTSP-4.2, you'll need to do the following:

 1) Copy your lts.conf file from /opt/ltsp/i386/etc to /opt/ltsp-4.2/i386
 2) Add  "/opt/ltsp-4.2/i386" to your /etc/exports file
 3) run  'exportfs -ra' to update the nfs daemon
 4) Modify your dhcpd.conf file as follows:
    a) Change the 'filename' parameter to point to the new kernel,
       it should be '/lts/' for PXE booting
       and '/lts/vmlinuz-' for Etherboot booting
    b) Change the root-path entry to point to '/opt/ltsp-4.2/i386'
 5) Restart dhcpd

That should take care of it.
