/Etc start running script

1. Brief description of the Startup Script

Start the super process in the init system
Inittab process STARTUP configuration file
RC0-rc6 startup scripts at various startup levels (the downtime level is 0, and the restart level is 6, the value is obtained by the initdefault id value in the inittab file in the/etc/directory from the INIT process. generally, the running level of the X11 graphic interface in Linux is 5. normally, RC means run control .)
Start script in single-user mode
Init. d Startup Script directory

2./etc/init. d and/etc/rc. d/init. d

The former is the soft link of the latter.

3. My Development Board file system etc

Only the/etc/init. d directory does not exist.

Because it is in single-user mode, you only need to create the script for starting and running the RCS in the/etc/init. d directory.
