	* null.c (main): Use trivfs_startup() instead of doing things manually.

	* null.c (main): Move the check for the bootstrap port after the
	args check, so that users can run it from the shell to get a usage
	message.

	* magic.c (main): Don't deallocate our right to the underlying
	disk node, so we don't get garbage collected prematurely.  Also
	move the check for the bootstrap port after the args check, so
	that users can run it from the shell to get a usage message.
