[Samba] Cannot write over root owned file

Unless you have "invalid users = root" there shouldn't be a problem.
Try creating a file instead:

 $ touch /mnt/tillie/tmp/test.txt

And then see who owns the file - it should be root (if you're connected
as root) but I suspect it'll be some other user.  You probably need to
specify the user when you connect, i.e.

 $ smbmount smbmount tillie/all /mnt/tillie -o uid=0,username=root

Cheers,
