The cluster machines differ from `debathena-workstation` machines in a few ways:

 * serial reusability ("login chroots")
  * Users get root privileges
 * larvnet (workstation monitoring)
 * central syslogging
 * software metrics
 * hardcoded printer list
 * session-duration-limiting software ("bugme", on quickstation only)
 * "thirdparty" software (a giant metapackage pulling in a ton of Ubuntu software)
 * screensavers lock after 10 minutes and can be logged out after 20.
 * A number of disabled services:
  * "fast user switching"
  * sshd
