NFS
From HostGISLinux
If you'll be using NFS, you'll want to install the portmap package, as NFS uses the portmapper. A symptom of NFS missing the portmapper is a very long hang during startup and compaints about rc.portmap not being found.
# for 4.2 slapt-get install portmap
# for 4.0 through 4.1 slackpkg install portmap
