I'm fairly new to Linux still, and I'm finding the subject of the history of how Linux managed, and now manages initialization. I've read all kinds of sources ,and I understand that the init system has moved from the older V system..to a few others and now is using upstart. But it's still a confusing mess in my head.
- Is this subject something critical to learn right away?
- And are there any older distros I can install into a VM to experiment with the older system which used init and the inittab file?
I just feel like I need to go back to the roots and learn that first, before I can understand the new upstart.
I know in Lubuntu, the init.d directory has a lot of links that reference config files in init. But I still don't understand how it all works because all these sources I'm reading mention files that are not there. I know inittab is long gone. I would really like to locate a "good" tutorial that starts from the beginning at the V system, and goes though the historical time line .. (while explaining things) how the system works. Everything out there I find is incomplete.
