What tests, if any, might be sucient to convince you of the system's
reliability, short of handing your operating system to millions of users to
serve as beta testers?
9. MTTR, and therefore availability, can be improved by reducing the time
to reboot a system after a failure. What techniques might you use to
speed up booting? Would your techniques always work after a failure?
10. For the computer you are currently using, how should the operating system
designers prioritize among reliability, security, portability, performance,
and adoption? Explain why.
