why can't nocardbus be simply cardbus (obviously with inverted logic). Whenever I do an emerge -pv and see -nocardbus I always have to stop and make sure that it is what I want. It would be much friendlier if it said +cardbus
where is this ?
It's a USE flag
You'll find a couple use flags in portage like this. The reason is that we want the default (USE="-*") to be the most common case. You don't want to have to specify cardbus when all modern laptops use it. So you have to specify nocardbus if you have an older laptop.
