I always thought /etc/rc.d/rcinit was the one, but I guess not!
NI

Yup, /lib/init.so is just a library, not the first program.

Wait, is it really /sbin/init? I thought it was something else.
CH

Agreed, that's the standard for SysV init.
BO

It's definitely /sbin/init!

I remember reading that SysV init uses /sbin/init, but I could be mixing it up with other init systems.

I’m not entirely sure, but I feel like /lib/init.so might be involved somehow, though it doesn't sound right for the first program.

I practiced a similar question last week, and I believe it was /sbin/init that gets called at boot time.

I think the first program started by the Linux kernel is related to init, but I can't remember if it's specifically /sbin/init or something else.

I'm a bit confused by this question. I know there are different init systems like SysV, systemd, and Upstart, and they might have different first programs. I'll have to review my notes on the Linux boot process to be sure I have the right answer.

I'm pretty confident that the answer is /sbin/init. That's the standard init program used in SysV init systems, which is the most common init system for Linux distributions. I'll mark that one down.

Okay, let me think this through step-by-step. The Linux kernel is responsible for starting the first program at boot time, and that program is usually the init process. Based on the options provided, the answer is most likely /sbin/init.

Hmm, I'm a bit unsure about this one. I know it has something to do with the init process, but I can't quite remember the specifics. I'll have to think this through carefully.

This is a pretty straightforward question about the Linux boot process. I'm pretty confident I know the answer, but I'll double-check my notes just to be sure.

The wording of these options is tricky. I'll need to read them closely and think through each one.

I'm a bit confused about the difference between AWS Step Functions and just launching jobs in parallel. Wouldn't option B require more setup than necessary?

This seems straightforward. Since Activity B is on the critical path, a 2-day delay in that activity will directly translate to a 2-day delay in the overall project completion.

Okay, I think the key here is to minimize downtime. Online migration to a new host seems like the best option - that way the application can keep running while we move it to a less loaded server.

This is a total gimme. If I don't know /sbin/init by heart, I might as well pack up my penguin and go home.
NO

Definitely a gimme question

If I get this wrong, I'm going to boot up my Linux machine and check it myself. I'm not taking any chances!
LI
Ling

Yes, that's correct! The first program started at boot time by the Linux kernel using SysV init is /sbin/init.
WI
Willard

B) /sbin/init

No, that's not correct.

Wait, is it /boot/init? I swear I saw that somewhere... Ah, never mind, I'm probably way off.
FA
Fatima

Definitely not E) /boot/init. It's B) /sbin/init for sure.
KA
Kami

Yeah, I remember reading that too. It's the first program started by the Linux kernel at boot time.

Aha! /sbin/init, of course! That's the one that starts up all the other processes. Easy peasy!
DE

Exactly! It's like the conductor of the orchestra, getting everything in sync.
LI
Linn

It's responsible for initializing the system and starting up all the other processes.
BO
Bonita

Yes, you're right! /sbin/init is the first program started by the Linux kernel.
TA
Taryn

Hmm, I was thinking it might be /etc/rc.d/rcinit, but I'm not entirely confident about that.
RO
Rolland

Definitely B) /sbin/init, that's the first program started by the Linux kernel.
TA
Tarra

Yeah, /sbin/init is the correct answer.
KA
Katina

I'm pretty sure it's B) /sbin/init as well.
RA
Ramonita

I think it's B) /sbin/init.
VA
Van

I'm not sure, but I think it makes sense that /sbin/init is the first program started at boot time.
JO
Jody

I agree with Darci. The Linux kernel usually starts /sbin/init first.
ME
Melodie

I'm pretty sure it's /sbin/init, that's the standard SysV init program, right?
PA
Patria
1 year ago
I remember reading about /etc/rc.d/rcinit, but I think that's not the first program that gets started.
HE
Heidy

Yeah, /sbin/init is the standard SysV init program that gets executed at boot time.
LE
Leonida

I always thought it was /lib/init.so, but I guess I was wrong.
DE
Della

Yes, you're correct. /sbin/init is the first program started by the Linux kernel.
DA
Darci

I think the answer is B) /sbin/init.
