If there is diff detected between the two harvests, and it can
enforce restoring the state from the older harvest, it will

`--ignore-package-versions` will skip reporting when packages are
upgraded/downgraded in the diff.
- Fix stat() of parent directory so that we set directory perms correct on --include paths.
- Set pty for remote calls when sudo is required, to help systems with limits on sudo without pty
