install machine

  * edit sudoers: comment out "Defaults targetpw"
  * uncomment 1st line allowing wheelgroup members to run commands.  **Do not** uncomment the line that allows wheelgroup people to run commands without a password.
  * Default install does not have NFS Client stuff, that needs to be added via YaST or zypper.  **Symptom** of not having nfs is the cryptic error message "mount.nfs: no such device".
  * edit /etc/dhclient.conf as per CentOS directions.
  * edit /etc/ntp.cofn add "server ntp.cs.wpi.edu iburst maxpoll 9"
