I'm using the directions here:
https://help.ubuntu.com/community/MythTV/Install/Hardy/Diskless
It mostly works. I can build the images and try to boot them. But the boot stalls. The only error message I see is "eth0: No link during initialization". It has a link, I just used it to load the kernel! :)
I'm doing this on my fileserver that's running Hardy LTS. I did an aptitude update and upgrade before starting this work. The server is working, DHCP is working, and I get a kernel and initrd to load. I get a Mythbuntu splash screen, then it goes black with a cursor. The message I mentioned before is from disabling the splash screen in the PXE setup. I don't see any messages about the root FS missing, so I think the NFS mount is working. I have other NFS mounts working from that machine. Is there any way to tell if the client is connecting from the server logs?
Any ideas would be great.
