[K12OSN] pxe booting

[Conrad Lawes]

Did you try issue mount nfs pkcentos:/opt/ltsp/i386
on the system that is failing?  In your mail, you state that problematic
system is trying to mount root to "system:/opt/ltsp/i386"
Make sure that your dhcp server is pointing to the correct ltsp server - in
your case this should always be pkcentos
