Re: [dvd::rip] Cluster Mode System Requirements

I'm responsible for the urging of not using "soft" in the docs. Why? It
was a never ending source of headaches -- and it took a few hours to
narrow down the problme to soft NFS mounts.

Even if you could get the WiFi to work with "soft" you WILL certainly
have problems with cluster mode with failed jobs. Dvd::rip currently
isn't smart enough to retry a failed job.

A solution that might make NFS work with hard for you is to use NFS over
TCP/IP only. Read the NFS docs for this, or the NFS Howto on tldp.org.
