Re: Customization of GRUB2

[Seth Goldberg]

Hi,

  I'm going to make an unpopular suggestion, so feel free to tell me to take a 
hike, but I think Bruce's question highlights a very important point-- the 
documentation that we have for GRUB2 at this point is very poor.  In order to 
continue to get new users to use GRUB2, we need quality documentation at least 
initially written by the people who authored the code.  User documentation is 
at least as important as the multitude of features that are pouring in, and I 
think we'll see a dramatic uptake of GRUB2 as well as a more-satisfied 
userbase with comprehensive documentation.  Feel free to flame me, but this 
is my opinion.
