Hi Jens,
this reply of mine went on bugging me, until I understood my mistake.

The fact that I consider bfq good also for servers *does not* imply
that having bfq in desktops is to be refused.

As for the option that you are hinting at, I also acknowledge that it
would be trivial for an admin/developer to know whether a given kernel
is meant for a desktop/personal system, while it is more difficult to
choose explicitly among the various I/O schedulers available.

So, I apologize for my shortsighted, initial reply, and ask you if can
elaborate a little more on this. I'm willing to help, if I can.

Thanks,
Paolo
