Non working solutions I've seen

• All workstations rsynced from central image

  • very heavy on the rsync server(s)
  • nightmare to maintain rsync includes/excludes
  • unsafe to upgrade libc
  • hard to maintain local software

• chroot live image with ssh/scp pushes

  • much better (install & clients in sync)
  • support for local software
  • disaster if some clients can be down since they miss updates

• nice install server with no updates

  • No comments...

• nice install server with push updates

  • what about clients that are down during updates?
  • install out of sync with pushed updates
