Talk by Thorsten Kukuk.

Problems

  • Update should not interrupt serivces
  • Updates either fully applied to not at all

  • Update is atomic: all or nothing
  • Update can be rolled back

Tools?

  • Btrfs progs

Snapshots

  • Seperate data and applications
  • Create a future snapshot
  • Install software
  • Rollback
  • Reboot
