Comment # 18 on bug 1199450 from Martin Vidner

Summarizing the report, there are problems with YaST scanning for servers AND
directories, when the firewall is enabled.

1. Scanning for servers ("Choose" button)

Neil says there is no reliable method for v4 servers.

2. Scanning for exported directories ("Select" button)

YaST has 2 methods for this, mount-and-find for v4, and showexports for v3. We
should fix the decision logic to use showexports only as the last resort.

3. Exported subdirectories of exported directories are not shown(?)
