You probably ought not to be booting LTSP clients if you want them to run 
mythfrontend. Since all LTSP processes effectively run on the server, you would 
be faced with running several mythfrontends on the same host, which could get 
interesting. Not to mention, LTSP uses the remote X functionality to display the 
desktops on the thin clients, and myth does too much for that to work properly. 
I know, I've played around with that in the past.

It is perfectly possible to serve both from the same system, however. I run a 
host which serves both LTSP clients and a diskless mythfrontend.

I think you should be booting minimyth (http://minimyth.org/) for your front 
ends. It is a relatively straightforward matter to add in the required files 
alongside those installed by the LTSP functions. You would also need to add 
extra lines to dhcp.conf to handle your dedicated mythfrontend clients. Because 
of this, I don't let my pfSense firewall run the dhcp, it's all handled by the 
master server, which in any case has to run tftpboot and other services for the 
thin clients. This has the added advantage of keeping the configuration all on 
one machine.

Hope this helps.
