Comment 59 for bug 946663

I'm seeing this bug, and I have neither NTFS partitions, nor a separate /home. I've told the installer to install everything in a single partition at /. I'm installing to a btrfs partition that I created outside the installer (because I wanted to enable the compress option and the installer won't let me do that) -- so the target root filesystem already exists. If I tell it to format the root partition, it works.

So this is a bug that only exists when the user choses NOT to format an install partition. Seems it could be / or /home (or probably anything else)
