Actually, that is a good question and consideration when choosing a boot loader.  Since I started using GRUB, I have not had to do a single user boot nor have I done any other special parameters.

All of that is just a long was of saying that I don't know the answer to your question.  I will have to look into it.

I couldn't see how to do this with Grub without going thru what seemed
like fifteen mind-boggling menus... has it changed?
