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
