During the boot process of ubuntu7.10, Linux learners should understand the Linux general technology-Linux technology and application information. The following is a detailed description. For more information about Linux versions, see

It seems that the init process in the system startup process has been replaced by upstar since ubuntu6.10, so the/etc/inittab file in the system disappears. Since ubuntu6.06, I have only used the system, I didn't notice these things. Today I heard this thing, but I really felt it was time to study it.

The current startup process seems to be:
0. The kernel starts the init process.
1. Enter/etc/event. d/, find the running level from the/etc/event. d/rc-default question, and run it by the corresponding running level script rcX;
2. When rcX is running, enter/etc/init. d/and find the script rc;
3. Execute rc X
4. After rc X is executed, it enters the/etc/rcX. d/directory and runs the processes in sequence.
