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
entry:

	thoreau 2> grep -r PTYFS */conf/[A-Z]???*
	i386/conf/GENERIC.MPACPI:#file-system PTYFS # experimental - /dev/ptm support
	thoreau 3> cat CVS/Tag
	Tnetbsd-3

and mount_ptyfs(3) says:

BUGS
     This filesystem may not be NFS-exported.  This filesystem is experimen-
     tal.

So using ptyfs for at least the 3.0 branch doesn't seem like an option
unless this is addressed.
