I am looking for PKI (Public Key Infrastructure) knowledge and particularly at OS's built-in certificate chain list.

Of course on Windows the company decides which certificate will be built-in, but what about OpenSource operating system like Linux?

That's OS specific. Any particular one you're interested in? Unix is a family of operating systems, Linux is the kernel found in another family of operating systems. – Stéphane Chazelas Feb 5 '14 at 9:39
What do you mean with CA? Certificate Authority? – user55518 Feb 5 '14 at 9:47
@StephaneChazelas So it is... – acgtyrant Feb 5 '14 at 10:02
That's an interesting point, you can assume that Trusted CA on proprietary UNIX are probably decided by the company who developed it. but for free OS like Ubuntu Debian or Centos, I have no clue how this list is established – Kiwy Feb 5 '14 at 10:05
It's up to the distribution maintainer. They can include any that they wish. But in practice, mostly the repackage Mozilla's list. – bahamat Feb 5 '14 at 10:17

I am using Arch Linux, and other users told me that it use the debian package which contains the certificate list compiled by mozilla, spi and cacert.

I am doubt that other Linux distro use the ca-certificate from Debian too.
