Having sane > defaults applies to the kernel as much as it does to userspace. Jeez. Don't mentione the desktop. On the desktop this is compleltely irrelevant. There are not TTYs on the desktop. There's no "make -j" of the kernel tree on the desktop. The kernel patch discussed here *has* *no* *relevance* for normal users. The kernel patch discussed here is only relevant for people which start mplayer from one terminal, and "make -j" from another. Lennart -- Lennart Poettering - Red Hat, Inc.
