hi.....

We know that when the linux system starts up ... its start them by satisfying dependencies between them,...


I would rather put my question through an example


eg: service vsftpd depends on service network rite???
So network is started before vsftpd is started.....


My question is whether starting up of network service should have just begun and we can start vsftpd or is it that vsftpd can be started only when the whole startup procedure of service network must have finished?????



also .... i remember reading the script of vsftpd.... it first checks whether network is up by checking a varibale 'networking' ..... when does this get set up????

any ideas????


thnks

Yeah, there is a dependence. But it is maintained manually. Ever open one of those files /etc/init.d and read them? in FC/RH, there is always a comment line
the num1 and num2 are integer which will be used by chkconfig to determine the order of execution of the script during boot up and shutdown.

Using your example, network is 10 and vsftpd is 60 (in my system). So it garantee that vsftpd is executed after network is done.

And since the boot up sequence is so far linear, vsftpd cannot only start unless previous one is finished.
