Normal System Startup

The /sbin/rc script sources all the files in the /etc/rc.config.d directory. The files in /etc/rc.config.d contain environment variables that control the startup and behavior of various processes.

The /sbin/rc script runs the scripts in the directories /sbin/rc0.d, /sbin/rc1.d, /sbin/rc2.d, /sbin/rc3.d, and /sbin/rc4.d, in that order.

The scripts in the /sbin/rcn.d directories are named SNNNscriptname, where NNN is a sequence number, and scriptname is the name of a startup script in the /sbin/init.d directory. Each of these scripts is actually a link to a startup script in /sbin/init.d. The /sbin/rc script runs them in order by sequence number. Following is a partial listing of the /sbin/rc2.d directory:

lrwxr-xr-x   1 root ... S400nfs.core -> /sbin/init.d/nfs.core
lrwxr-xr-x   1 root ... S406nisplus.server -> /sbin/init.d/nisplus.server
lrwxr-xr-x   1 root ... S408nisplus.client -> /sbin/init.d/nisplus.client
lrwxr-xr-x   1 root ... S410nis.server -> /sbin/init.d/nis.server
lrwxr-xr-x   1 root ... S420nis.client -> /sbin/init.d/nis.client
lrwxr-xr-x   1 root ... S430nfs.client -> /sbin/init.d/nfs.client

All the startup scripts for the NFS services are started at run level 2 except the nfs.server script, which is started at run level 3. Table 8-2 “Startup Scripts for the NFS Services” shows the NFS, NIS, and NIS+ startup scripts, in the order they are run at system startup. It lists the processes that each script starts and the files and environment variables in /etc/rc.config.d that influence their behavior.

All of the startup scripts start rpcbind if it is not already started, but only one rpcbind process should be running at once.
