> I go my RHCE 5 years ago and it was a great primer on how Linux systems run and I recommend it to anyone interested in modern Linux. It will give you many insights which will help you in the future in understanding how Linux works. I was moving over from Windows administration and it was a godsend.
I'm not sure it entirely still works, but for anyone that wants a much deeper look into how a system Linux is put together and how a lot of the parts interact (at a higher level, but still a level often not covered), check out the Linux From Scratch project.[1] Around 2001 or 2002 I was helping to design a small custom Linux distro with some friends, and going through this project was invaluable for learning a lot of how a GNU/Linux system was put together and functions as a whole.
There really is something to be said for manually going through every step, and compiling every software package, and experiencing the functionality it provides, since a good chunk of the work is done in a chroot after you've bootstrapped it enough to make it minimally viable.
