I mixed up them intentionally, because you said that the GNU way was 
easy to implement. I showed a simple example that the GNU way was not 
easy actually.

If you follow the GNU way, your parser or the implementation of a 
command function must be complex. If you make your parser easier, the 
burden would just move to one who uses your parser.

That's right. That's the very thing I wanted to mean.

I still think it would be better to use the POSIX way than the GNU way, 
to make everything easier and simpler. As most people don't use a boot 
loader interactively frequently, this should be a good decision.
