 It doesn't look like ptyfs is an option for the 3.0 branch.  The only
 reference to it in _any_ kernel configuration file is this commented out
 	thoreau 2> grep -r PTYFS */conf/[A-Z]???*
 	i386/conf/GENERIC.MPACPI:#file-system PTYFS # experimental - /dev/ptm support
 	thoreau 3> cat CVS/Tag
 and mount_ptyfs(3) says:
      This filesystem may not be NFS-exported.  This filesystem is experimen-
 So using ptyfs for at least the 3.0 branch doesn't seem like an option
 unless this is addressed.
