Yes, that would happen. But this issue is independent of whether the 
symlink points into a mounted directory because you'll get the same 
error with set-file-modes with nofollow on a symlink into the same 
directory. That's the point of nofollow: you don't want to follow the 
symlink.

The error that prompted this bug report is that I mistakenly added 
nofollow to a set-file-modes that was actually intended to follow a 
symlink, and my mistake was independent of whether the symlink points to 
a mounted directory.
