Hey guys,

I'm new to gentoo.. Was wondering if anyone has a diagram of gentoo's loading process..

It will help me draw a mental picture. Yes I'm weird that way. I like to picture where and when processes can go wrong..

Thanks

Hey Thanks for the reply...

But I fail to see where this link provides a Diagram of the booting process for gentoo linux...

What I saw in GitHub was a community of programmers that share there codes and ideas combined with I guess GitHub platform...
I'm looking for a PDF of some-sort...

Thanks

Why not have a look at the log files from your machine booting?

How do I do that... And will the log files describe at what point a process begins and when it ends..?

Thanks

I don't think such documentation exist. But you can get pieces at many places.

You can get a first idea at : http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=2&chap=4

This is not up to date if you use systemd.

Other than that you could read documentation from LFS project : http://www.linuxfromscratch.org/lfs/view/stable/

Linux from scratch will give you an understanding of what is done by the OS at boot time.

You won't find such a diagram as it would be different for every Gentoo machine which is why Ant P. suggested bootchart2 which will create a diagram for your machine.

You can install bootchart2 with Portage:

Code:
emerge bootchart2


Once it's installed the man page will tell you what you need to do to get a chart of the boot process.

Hello,

The process is quite generic and not gentoo-specific.

After reading this post I got curious and installed bootchart2.
Had to add a few things to my kernel config.
Works like a charm.
Still have to figure out what it all means.

Well, it's not exactly what you're looking for, but I noticed the following article (which includes a PDF link) this evening whilst browsing tuxmachines.org:

http://www.expertslogin.com/booting/linux-boot-process-chart/

Just thought I'd mention it in case it is of interest.
