还有一个地方就是系统启动时第一个进程通常都认为是init,但是实际上感觉应该是swapper进程,在《The Design of UNIX OS》这本书中提到就是:" rocess 0 is a special process that is created "by hand" when the system boots; after forking a child process(process 1), process 0 becomes the swapper process. Process 1, known as init, is the ancestor of every other process in the system and enjoys a special relationship with them,... ..."
还有启动方式目前System V和BSD两种风格,大部分GNU/Linux版本都使用system V风格,也就是/etc/rc.d/rcN.d/S or K[num]process的风格,好像只有slackware是使用了BSD风格,所以有些人说slackware是GNU/Linux的“叛徒”呵呵。不过两种风格大体上差不多。 受益非浅

没有装过slackware,不知道BSD风格怎样 |
