Review Board


This cleans up the docs for upgrading Review Board and site directories.
Most of these changes are pretty minimal, involving:

  • Moving to code-block:: console.
  • Providing some additional details on needing to be root.
  • Removing the step for restarting memcached (as we're better at key
    management these days).
  • Moving to itemized lists of steps.
  • Including the SELinux steps during site upgrade.

The "Troubleshooting Upgrades" section has been removed, as it's no
longer applicable. There is a blurb at the right upgrade step to give
users direction if upgrades fail, though.

Built the docs and read through them. Checked for spelling errors,
bad links, and build errors.
