I was in need to setting ownership for some extra files and will probably need it more going forward so I added a --chown option and documentation too.

Ignore my previous message, everything looks good! Let me know if anything more needs to be done.

I'm a little unsure as to what to do. One of the tests failed due to a kernel panic, and I can't imagine that's due to my PR. Any comments or pointers would be greatly appreciated.

No action required. This is general flakiness because we are close to the memory limit for some reason.
