  • (paraphrase): "The insight behind Rainbow is that the problem of isolating an operator from his/her programs is similar to the problem of isolating users of a shared server from one another and from root." -- C. Scott Ananian
  • "I see the cool parts [of Rainbow] as (1) per-instance isolation, (2) isolation without virtualization, and (3) isolation using the uid mechanisms. All three are unique and impressive." -- Ben Schwartz
(NB: Actually, lots of other people have played with these ideas. plash is a compelling example.)


  • Give people an isolated Terminal to play in.
  • Show off rlimits with a fork-bomb.
  • Show off filesystem protections -- rm -rf, restriction of readable dirs, etc.
