Good! We're all set on the local end, but now we need to know
where to find the software packages to install. First, we need
the IP address of the machine where the Slackware sources are
stored.

 There must be a directory on the server with the Slackware
 packages and files arranged in a tree like the FTP site.

 The installation script needs to know the name of the 
 directory on your server that contains the series'
 subdirectories. For example, if your A series is found at 
 /slack/slackware/a, then you would respond: /slack/slackware
 
 What is the Slackware source directory?

If you see errors and you don't see your NFS server listed,
then try setting up NFS again.
