There are at least 2 ways : 1) copy-paste code 2) read specs, implement them - following the directions FSF paper gives. The result might be the same code, but the way to get it matters too.

You must understand that we are volunteers. We very much prefer not being sued to taking risk only for your computer. You say "new PCs", but this wording is too brave.

We prefer assigning copyright to the FSF, but this does not mean that we may not use others' code. The important thing is that we must carefully treat who owns which code, so we must separate code into different files when we reuse code written for other projects. This is only _my preference_, but I would like to keep critical parts of GRUB owned solely by the FSF. So, for example, I do not care about the copyright of a filesystem very much, but I do care about the copyright of bootstrap code. In the case of the A20, I'm not sure how I want to implement it. It is not that bad to use syslinux code, because we have our own alternative. However, this code is very critical, and I prefer writing our own code. After all, my opinion looks like the same as Marco. :p > There's no such requirement in the GNU GPL !

It does not define how a project should be managed. Okuji ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
