SmartQV3Ubuntu system startup Analysis

In the analysis of SmartQV3Ubuntu system startup, first confirm the default running level: run on the terminal after the system is started: user @ SmartQ: /etc $ runlevelN2 compare my Fedora running level [www.linuxidc.com @ linuxidc ~] $ Runlevel

For the analysis of startup of the SmartQ V3 Ubuntu system, first check the default running level:

Run on the terminal after the system is started:

1. User @ SmartQ:/etc $ runlevel
2. N 2

Compare my Fedora running level

1. [Www.linuxidc.com @ linuxidc ~] $ Runlevel
2. N 5

Not the same. In fact, later I found 2 ~ Of This V3 ~ 5 is the same. :-). It will be mentioned later.

1. Www.linuxidc.com @ SmartQ:/etc $ ls rc *
2. Rc. local
3. Rc0.d:
4. K05preload S01smartq S20sendsigs S35networking S90halt
5. K74bluetooth S10unattended-upgrades (S30urandom S40umountfs)
6. README S15wpa-ifupdown S31umountnfs. sh S60umountroot
7. Rc1.d:
8. K05preload K74bluetooth README S30killprocs S90single
9. Rc2.d:
10. README S25bluetooth S95preload S99ondemand S99rc. local
11. Rc3.d:
12. README S25bluetooth S95preload S99ondemand S99rc. local
13. Rc4.d:
14. README S25bluetooth S95preload S99ondemand S99rc. local
15. Rc5.d:
16. README S25bluetooth S95preload S99ondemand S99rc. local
17. Rc6.d:
18. K05preload S01smartq S20sendsigs S35networking S90reboot
19. K74bluetooth S10unattended-upgrades (S30urandom S40umountfs)
20. README S15wpa-ifupdown S31umountnfs. sh S60umountroot
21. RcS. d:
22. README S03smartq S55urandom S70x11-common S75policykit

So here we can see that the contents in the directory rc2.d to rc5.d are exactly the same.
