Oh, you were asking me to do something? I was pretty sure you were asking for
your hand to be held. As it is, the only reason I'm not building another Linux
is simply that I'm waiting for the next version to come out, and it's quite
overdue. Now, if you actually want help, stop insulting the people trying to
help when you're acting like you won't help yourself.
Off to build the center console of a Lexus.
