/etc/rc2.d vs /etc/init.d

Hi,

Can somebody please tell me the difference between the files in /etc/rc2.d and those in /etc/init.d? I am asking because on one system, I got a sysedge file S99.sysedge under /etc/rc2.d and it has a soft link to the /etc/init.d/sysedge.
It would be my understanding that the one under /etc/rc2.d would be used at the system reboot and the one under /etc/init.d would be to allow us to manually stop and start sysedge. Please shed more lights on this for me

Thanks,

you can think of it this way: rc2.d is for run-level 2

Do you suppose that init steps through run levels -> 3 when it boots up?

/etc/init.d is a convenient repository directory. It is not used by init which only scans the rc*.d directories for start and stop scripts. These ones are often soft links to init.d but aren't required to be.

This is described at length in "man rc".

Thanks guys for your response.

Jim,

Yes, I supposed that init runs through run level 3.

Jllagre,

Good to know that rc*.d aren't required to be soft links to /etc/init.d ....That's what i wanted to know.

Methyl,

cannot find a man page for rc as you suggested above.

Thanks again all,

That's
Code:
man init.d

on Solaris.
