Response to: Tweaking kernel

The point of kernel extensions in the I/O Kit is to allow Mac OS X's kernel to dynamically load device drivers as needed when booting. Linux can't do this.


Um, Linux has had dynamically loadable kernel modules for a long time. So has FreeBSD. So has Solaris and about every other contemporary Unix I can think of.

    The problem with Linux is that you cannot ship a precompiled kernel module - it would not work with a slightly different kernel. On Mac OS X, most kernel extensions for OS X 10.3 still work in OS X 10.4, even though 10.4's kernel is much newer.
