Re: Mythtv diskless karmic.
I followed the guide in the link with a few tweaks/clarifications.
I was finally able to get this up and running. I first tried to use my router(Linksys WRT54G running Tomato 1.25) as the DHCP server and my backend(jarule) as the ltsp. I could not get the router to redirect to my backend server. I decided to try the "standalone" approach, in other words, making the backend a DHCP server and turning off the router DHCP. I then built the image using
sudo ltsp-build-client --mythbuntu --mythbuntu-user-credentials <username>:<password>
Username must not be "mythtv" as this will cause the above to fail. Likely due to the fact the mythtv packages add mythtv as a user during setup and then ltsp-build-client fails fatally on its own "Adding user mythtv".
I added to /etc/exports
/opt/ltsp *(ro,no_root_squash,async)
/var/cache/mythbuntu-diskless/overlay *(rw,no_root_squash,async,no_subtree_check)
I was finally able to log into the system as <username>, (hopefully i can edit /etc/gdm/custom.conf for autologin for username mythtv). I then installed the nvidia drivers using the diskless client and rebooted(hard reset). I also had to
dpkg-reconfigure tzdata
to get the mythfrontend to run. It didn't like the client being on a different timezone.
LiveTV worked well on both HD and non-HD. HD was a little jumpy at moments but watchable(maybe something I can tweak on the network).
A big problem is that it hangs on shutdown.
Frontend client is an Zotac ION A-U. About the same bootup time as a locally installed version of Mythbuntu. 30-60 seconds.
