本文探讨了Linux内核的独特之处，包括其不采用传统libc库、内存保护机制的缺失等特点。虽然初看起来似乎难以驾驭，但文章鼓励读者深入了解并修改源代码，以克服初期的畏惧心理。
The kernel is indeed a unique and inimitable beast: No memory
protection, no tried-and-true libc, a small statck, a huge source tree.
The linux kernel plays by its own rules, running with the big boys and
stopping just long enough to break the customs with which we are
familiar. Despite this, however, the kernel is just a program. It is
not very different from the usual, the accustomed, the status quo. Do
not be afraid: Stand up to it, call it names, push it around.
Realizing that the kernel is not as daunting as first appearances might suggest is the first step on the road to having everything just make sense. To reach that utopia, however, you have to jump in, read the source, hack the source, and not be disheartened.
