Repo-specific developer documentation

  • Illumos integration process
  • Information about how to develop ZFS for the different distributions/pointers to them (e.g., how to build illumos)
    • in particular, documentation about how to test and possibly scripts for building
    • needs to be written/links provided by reps from those communities.
