What to read in depth?

Question

linux

Don't throw stones at me :)
I've been a windows administrator for a long time, but from year to year, more and more often I have to work with Linux. At first there were just service FTP servers, then Zabbix + nginx, now Asterisk. Of course, in parallel, I somehow study the system itself (I usually use CentOS). But sometimes you still want to read something that will specifically talk about the internal mechanisms of Linux. I would like some modern book about the system itself ... please advise if someone came across something sensible. Preferably in English.
For example, here are a few questions that I would like to see answered in the book:
Do I need to restart Linux after package updates?
Why in Linux, when the application \ service is closed, the memory is still shown as busy?
What is the difference between modern Linux file systems?

Well, etc.

Answer 1

I, at one time, was greatly pumped by the assembly of lfs with thoughtful reading of the documentation and analysis of the need for each package

Answer 2

Gentoo Handbook. Try to put it on. At first it was simple, then root-on-lvm-on-softraid, so that it was arranged “like a production system”.
I'm serious, everything is chewed up there, but study in practice what exactly the installer does and how the system functions after that.

Answer 3

Hello.
Google for the query "Linux manual" displays more than a sufficient number of articles. In English, there are probably even more all kinds of materials.
Put some build of GNU / Linux on your work and home computers as the main OS - get an experience that is much better than bare theory. Windows can be run in virtualbox. You can start with ubuntu or kubuntu 12.04.03. When you get comfortable, try building Gentoo.
