• Always dismount filesystems and try cleaning up when exiting and in jail -k
• For stage_orphans, ignore modified files (such as nobody vs root)
• testport -I: Mark cleanup done, not as recursively failing
• testport -i: Use a local.conf instead of PACKAGESITE

• options: Require dialog4ports as it runs from host and jail may be for a different ARCH
• Ignore parents of home directories too during leftovers check
• Ignore /var/db/dbus/machine-id leftover
• Restrict ZFS on 9.0/9.1 due to known deadlock
