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.
