Although the structure of system initialization is the same, it is interesting to note that the developers managed to make it faster. Instead of executing the files in /etc/rc2.d, the script /etc/init.d/rc can now source (read) them, without spawning another shell. Whether to execute or source them is controlled by the file name: executables whose name ends in .sh are sourced, the other ones are executed. The trick is shown in the following few lines:
case "$i" in *.sh) # Source shell script for speed. ( trap - INT QUIT TSTP set start; . $i ) ;; *) # No sh extension, so fork subprocess. $i start ;; esac
The speed benefit is quite noticeable.
