Re: How to change menu entries in grub?
Grub 2 reads various files for its naming system. Files such as
/etc/issue, /etc/lsb-release, /etc/debian-version, and various others
all contribute to what you are refereing to. There is a page somewhere
written by Paul (pabs) maybe in the census that tells maintainers what
files they need to change so not to infringe Debian copyright notices.
I suggest you locate it and read it and then change the files
mentioned and you'll probably find you don't have this difficulty
anymore.
Cheers.
Michael.
