Indeed it is.

I know what the problem is. The filesystem of /small/* is different to the 
one containing the symlink /home. We need to use lstat rather than stat to 
identify the parent directory's filesystem when it's a symbolic link.

You could change your backup locations to use /small/home instead of 
/home. I'll look into fixing the test for the next rc.

Cheers, Chris.
