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

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

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.

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.
