Nice to see someone mention this. Sometimes I think I am the only one. This sort of thing is what scares me away from GNU/Linux whenever I try it, having spent so many years with a BSD that does not enable anything by default. Nothing wrong with customization, except when it is someone other than the user who is fiddling with it.
I am used to a black background. Seems like the logical "default" starting point in VGA textmode. Even Linux kernel output when booting starts on a black blackground.
