First , let me ask you a few questions.
Why do you ask this kind of question without even trying to find the answer doing a search ?
Once the OS has booted, why does init process need to keep running?

Which init system are you referring to ?
And what makes you think it keeps running ?
From 1 of the many "educational" results, in the above search string.
After it has spawned all of the processes specified, init goes dormant, and waits for one of three events to happen:
It appears you started using Debian in 2011-11-24 00:17, at least that is when you joined this forum, so my last question is :
Have you ever read this:Please Read.. What we expect you have already Done ?
If you have not read it, please do. If you have read it, Why don't you try searching a little , before asking a question ?
johnywhy, why don't you search before asking ? Please tell us, I can't wait to hear the excuse.

Re: Why Init Keeps Running?

my apologies.

i did search, and found that all processes are spawned by init during the boot process.
https://en.wikipedia.org/wiki/Linux_startup_process

as i understand, that means init is the main thread, and all other processes are within that thread. is that correct?
Which init system are you referring to ?
My bad, I should have said, whatever init is used in the current Debian Stretch release. If there's more than one, sorry for my ignorance.

As you quoted, "After it has spawned all of the processes specified, init goes dormant, and waits for one of three events to happen". Also, the init(8) - Linux man page states:
it is the parent of all processes whose natural parents have died and it is responsible for reaping those when they die.
https://linux.die.net/man/8/init
I'm guessing that "reaping" means garbage cleanup and other termination-processes. Based on that, it sounds like init isn't just for booting. It orchestrates all process throughout the entire booted session, either directly or indirectly through their parents, including shutdown. Correct?

If so, then the Wikipedia page you quoted seems misleading. The page is called "Linux startup process". It states "Linux startup process is the multi-stage initialization process performed during booting a Linux installation." This gives the impression that init is just for booting.

as an experiment, i killed init. The OS shutdown.

This question pertains to a custom distro based on DebianDog

it's unsure whether this OS is booting from systemd or sysvinit. The maintainer is currently investigating.

what makes you think it keeps running ?
i believe init keeps running because i see a running process, ID 1, called "init[2]". Does that surprise you? I'm getting:

Please don't provoke the jibjab bot, it is very sensitive.
Once the OS has booted, why does init process need to keep running? THX
The answer to your question is, "because it's better that way."

I run a pretty plain default debian stretch system, and I don't have init running currently. If you are running another distro, or a non-default debian installation, then whoever set it up will know how it is set up? I'm not sure what the issue is about init?

Code: Select all

$ ps -ely | grep init
S  1000  2931  1795  0  80   0  1200  5578 -      tty1     00:00:00 xinit
Are you sayng that you are using a debian-based distro and the maintainer does not know whether he is using SysV or systemd as init? That seems almost impossible.

Help Lesson #105 Why Init Keeps Running?
Yes of course, you are right. I will try to keep that in my memory.
"Must try to not sound angry", I am sorry, and am not angry.
I am sorry, my english is not that good, and I sometimes have other problems,so my response might not be perfect.
The various init systems are: System V Init, SystemD, Upstart, Open RC, runit,
and there are others but not worth mentioning.
There was a recent topic here on this forum, about using Open RC, as a alternative on Debian.
The current Debian Stretch release uses sytemd by default, but it can be modified to use another.
The init system can not completely be shutdown, because it is needed for some processes, including the processes when the system is shutdown, so it is dormant, until something occurs that requires it.
as an experiment, i killed init. The OS shutdown.
Yes , that is logical, I would expect that.
This should show you what init system you are using:

Code: Select all

$ init --version 
or

Code: Select all

 stat /sbin/init 
i believe init keeps running because i see a running process, ID 1, called "init[2]". Does that surprise you? I'm getting:
Not at all, Dormant, waiting, is not the same as not running. The system will not run if
the 1st PID is not running, try using the 'top' command, it should show, "wait" or even sleeping ,..

Code: Select all

PID USERNAME PRI NICE  SIZE   RES STATE     WAIT      TIME    CPU COMMAND

            1 root      10    0  384K  428K idle      wait      0:01  0.00% init
 
Your thankyou and hope good day has you.

Great. Just when i thought i was starting to understand this, you guys give me more information. :lol:
bw123 wrote:I run a pretty plain default debian stretch system, and I don't have init running currently.
Hrm! Does your OS boot with it? Are you on Jessie? I read systemd is default starting with Jessie.
https://www.tecmint.com/systemd-replaces-init-in-linux/

So, a systemd OS will not have init, right?
Are you sayng that you are using a debian-based distro and the maintainer does not know
Apparently, they're 'building on the shoulders of giants'. Self-taught, i guess :D

I do see systemd process, so seems to be a systemd setup. So i guess should not be seeing init, eh?

Very helpful!

I will look for that! I want to run a very low-RAM xfce.
The init system can not completely be shutdown, because it is needed for some processes
You mean on a non-systemd OS, right?
it is dormant, until something occurs that requires it.
i noticed that it's CPU is 0, but it still occupies RAM. I'd like to make it go out of RAM until needed. Can it be hibernated, or terminated and restarted when needed?
try using the 'top' command, it should show, "wait" or even sleeping ,..
great info!

i have:

i think you already answered the "why" there.

this might shed more light on the confusion:

Code: Select all

# ls -l $(which init)
-rwxr-xr-x 1 root root 43532 Feb 12  2017 /sbin/init
Now i understand why init stays resident.
Part of my confusion is that both init and system are running.

Code: Select all

i think what's happening is that init was installed as the init (why do they have the same name?).
but, systemd is bundled with this OS, even tho it's not the init, cuz some processes depend on it.

as an experiment, i killed a systemd process. The OS shutdown.

But i can't tell what's using it:

Code: Select all

# whereis systemd

Try this :

Code: Select all

 man init 
And let us know what the first part of it says.
====Edited===
But it also would be educational to read the entire manual, take your time,
read it carefully.
The way I see it, a wheel is still a wheel, no matter what kind of rim and /or tire one puts on it. Init is like the wheel, systemd, runit, openrc, and all the other init systems, are simply different brands of rims and tires, that can go on the same wheel.

No , actually we didn't, but ok , no matter,... if you don't want to show what it says, that's fine.
There was some mention of what it says here: https://linux.die.net/man/8/init

But I mean, what it says on your system, when you use the 'man' command,
not , what some website says.

Code: Select all

$ man init

i wonder why it's different on yours.

also

       systemd, init - systemd system and service manager

SYNOPSIS
       systemd [OPTIONS...]
etc.

i believe what's happening is, this distro was made to boot with init, not with systemd.

systemd is only included cuz some packages depend on it. But it doesn't run the OS.

`man init` takes me to the web doc.

preferably in your opening post if you ask a question.
if you keep deliberately omitting that you will create a lot of bad blood.
