Hello,

I'm trying to learn how ostree deals with file corruption so I set up scenario where a library in /usr/lib is modified/corrupted and now ostree fsck is reporting a corrupted object.

I'd like to know if it's possible to checkout the original version from the ostree repo and wipe any corrupted/modified files that are currently live.

Thank you,

Davis
