CentOS(9) script

This repo is a centOS script for BPC-SOS project (make Linux OS as smallest as possible with some sort of GUI, where u can show vut webpage and some pdf).

• it aims to install xorg, browser, pdf reader and reduce the OS as much as i am capable of.
• I am kinda expecting, that u have installed minimal centOS (with no gui etc)
• If you dont know, how to install the minimal CentOS (its for centos8, but it should be the same). Here is tutorial: click me

It should work with centos8, if u uncomment the mirrors for centos8

How to make it run?

• If needed, install git: dnf install git
• On centos9, there are issues with sha1 signature, to fix this, execute these commands and reboot:

update-crypto-policies --set LEGACY
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

• Start script with:

sh <where_you_clonned_repo>/BPC-SOS/centOS.sh 

example: sh ~/BPC-SOS/centOS.sh

• You can switch to testing branch with: git switch Testing (You need to be in BPC-SOS/ directory).
  
• With git branch you can view your current branch.
  
• git branch -r Will show all branches.
  

How to launch Browser and PDF reader

• launch browser:
  • First step: start xorg and xterm with command startx
  • Second step, when you succesfully launched cli, you just need to type palemoon and browser should launch.
• Launch PDF reader:
  • Once again, you need to launch xorg and xterm with startx
  • Then to start pdf reade, simply type: gv <name_of_pdf.pdf>

  PDF should be in cd ~/

What exactly does this script do?

I will write down all things as i manage them to work like i want to :-)

• Install xorg apps + xterm, make sure xorg works (simple thing, its not bulletproof) and setup .xinitrc(minimal basics).
• Install webbrowser and some PDF reader
• [Failed] add testing for working webbrowser and pdf reader
• Set ut removing .cache and other useless stuff when system boots -> for now in .bashrc (until i find better way)
• removing whole bunch of random packages until i dont have anything more to delete :-P

kinda done, i know about some more spaces where i can delete some more, but there is no time :( and some more stuff
