\begin{pset}
  If the automounter used only one symlink, it would have to delay a
  \texttt{READLINK} on \texttt{/sfs/newfs} while \texttt{mount(2)}ing
  the filesystem on \texttt{/sfs/newfs}, then return a link to the
  same location. This would not work because the kernel's vnode
  locking strategy would require \texttt{/sfs} to be locked during the
  \texttt{READLINK}, causing the \texttt{mount} to fail.
