The linux system has 7 init level (0 and 6 are halt and reboot). If the init level of your linux is 3, sysinit will check all the scripts in rc3.d/ and start all the S* script. But you can change the init level (from 3 to 4 for example). And then, the sysinit dameon will look at the scripts in rc4.d directory. That's why you have several scripts. But the autofs stuff is only launched once. -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
