[mythtv-users] Problems with system-config-netboot Creating Diskless Myth Frontend

I had this.
I guessed that it wasn't finding the NFS export for some reason (set up similar to yours), so found a temporary workaround - change:

> /opt/m10k/root		192.168.1.18(rw,sync,no_root_squash)

to:

/opt/m10k/root		*(rw,sync,no_root_squash)

i.e. replace the client's IP address with '*' for 'all machines'. Then restart the nfs server and try system-config-netboot again.

This is a bit of a security no-no so put the IP address back once system-config-netboot is done.

Cheers
Neil
