[Bug] Fail to import a book

[szinn]

What Went Wrong?

When I try to import a book from the bookdrop, it creates the directory for it but fails with the exception

How Can We Reproduce This?

1. Grab metadata
2. Finalize

What Should Have Happened?

Would expect book to be imported

Turning on debug mode and watching the filesystem, the file is copied successfully to /tmp, the directories are created, but the move to the final destination comes back as 'operation not permitted'.

A suggestion would be to actually copy it since it could be across different filesystems and then remove the temporary file perhaps?

[szinn]

Verified that this is likely the problem. On my configuration, /tmp is a temporary memory drive. I moved /tmp to be on the same nfs server as the books and the import worked fine.
