Another option would be to use pxelinux configuration files to handle the differences, and then symlink the configuration file for each client. So in the top-level tftp dir, you'd have configs like so: /pxelinux.0 # symlink to ltsp5 configuration /pxelinux.cfg/default -> ltsp5 /pxelinux.cfg/ltsp5 /pxelinux.cfg/ltsp42 # symlink for mac address 11:22:33:44:55:66:77, note the 01 prefix: /pxelinux.cfg/01-11-22-33-44-55-66-77 -> ltsp42 # symlink for mac address 88:99:00:aa:bb:cc, note the 01 prefix: /pxelinux.cfg/01-88-99-00-aa-bb-cc -> ltsp5 Here's an example of a pxelinux configuration using probably overly complicated menus: https://github.com/freegeek-pdx/netboot-config/tree/master/pxelinux.cfg In particular, here's a setup for an LTSP configuration not in the default directory, forcing the nfsroot to a different value: https://github.com/freegeek-pdx/netboot-config/blob/master/pxelinux.cfg/diskless-terminal label ltsp-wheezy menu label Diskless Terminal kernel /ltsp/i386-wheezy/486-vmlinuz append ro initrd=/ltsp/i386-wheezy/486-initrd.img init=/sbin/init-ltsp quiet root=/dev/nfs ip=dhcp boot=nfs nfsroot=/opt/ltsp/i386-wheezy/ ipappend 2 You could easily have one configuration file for ltsp5 and one for ltsp42, and only make a symlink in pxelinux.cfg, rather than editing dhcpd.conf and restarting dhcp every time you add or remove a client. Also, with the "default" entry symlinked to whichever you prefer (ltsp42 or ltsp5), you would only have to add mac address symlinks for the non-default ones. Good luck! live well, vagrant
