I'm trying to configure an old 64-bit desktop machine as a client for a CentOS server. The client must have no modifiable storage at all so my options seem to be: 1) Stateless network boot 2) Live DVD I've been looking at the latter route, does anyone know if there is a convenient hook so that the live dvd will automatically download and execute a file during bootstrapping? I need to have some state, but held on the server. If there are any instructions for hacking the CentOS live dvd, please point me at them. I'd prefer not to go for a complete stateless network boot, the server will be booted in a number of configurations and it would mean reconfiguring xCAT or similar on each set of disks. Just to be even more awkward, there is no external network connection to the server, which will be running a 64-bit variant.
