Sure if you can solve the problem in a different way it is fine. I just said then when I did software development on ARM building the software on an x86_64 host was the only obvious choice. So it sounds logical to apply it here where the goal is to build a *whole operating system* and not just a specific program.

As I said in the other mail I am fine with that. I just had to respond to the "man-decades" hyperbole. (Maybe I should have just ignored it). -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
