/etc/rc:
> -mount -a -t nonfs
> +mount -a -t nonfs -o rw

This should not be necessary.  The "rw" should be in the /etc/fstab file.
Why did you need this?

/etc/ttys:
> -console	"/usr/libexec/getty Pc"		vt100	off secure
> +console	"/usr/libexec/getty std.9600"		vt100	on secure
>  
>  # Define the console that we actually run getty on.
> -ttye0	"/usr/libexec/getty Pc"		vt100	on secure
> +#ttye0	"/usr/libexec/getty Pc"		vt100	on secure

It is a minor correction, but I'd turn ttye0 off instead of making the line
into a comment.  You might also leave the console turned off and make the
tty00 line on, secure and std.9600.
