Bug#545518: grub2: Please add all optional, user-defined variables in /etc/default/grub

[Julien Valroff]

Package: grub2
Version: 1.97~beta2-2
Severity: wishlist

Hi,

Would it be possible to add all optional, user-defined variables in /etc/default/grub,
along with a short explanation of what they do?

I wanted a "hiddenmenu" and found many scripts from Google, but saw that it was already 
implemented thanks to the following variables:
GRUB_HIDDEN_TIMEOUT 
GRUB_HIDDEN_TIMEOUT_QUIET

They were added recently: http://www.mail-archive.com/grub-devel@gnu.org/msg11980.html

I haven't checked if other variables were added in the meantime, but if it is the case, they
should also be added to the default file.

Cheers,
Julien
