This is specifically how we want it. By removing fixed-id from your volume
graph at a later point, the filesystem continues as if fixed-id was never
loaded in history.

I'm interested to know what the exact issue is. I would prefer to have it
fixed in such a way that the filesystem stores the file owned by the real
uid/gid rather than the masked value.
