• Theory
  • Lin Booting process
  • Re-install linux fast
    • Ansible
      • learning curve
      • great control
    • Clonezilla - duplicate partitions to other systems
      • simplest
      • probable that the system won’t work because it’s configured with different hardware
      • not easiest to make changes w individual machines
      • bandwidth intensive
    • ArchISO - custom iso
      • Not as flexible for making changes post-deployment
    • custom installation script
      • great control
      • time-consuming
      • example bash script dotfiles - src
    • virtual machine
    • cloud images
  • basic
    • ways to install
      • Main repo
      • AUR
      • compilation usually trhough repos
      • docker
      • nix?
      • specific distro package
        • .deb
      • Virtualized thinghies
        • appimage - kinda like a slower docker
          • runs on different distros
          • doesn’t need sudo to install
          • self-contained & has its own dependencies
          • decentralized - no central store like others
            • but there exist appimagehub
          • big in size & memory footprint
        • flatpack - by redhat
          • flathub
        • snaps - worst
          • closed source…?
          • by Canonical, the company behind Ubuntu
          • snap store
      • downloading binaries - discouraged for security
    • Lin folders-file structure
    • Partitioning nd FS creation
    • Package managers
    • Lin troubleshooting-debug
    • lin security
    • systemctl
  • Scripting
    • Cron - systemd timers
    • Bash - lin commands
  • Other
    • HT learn best
      • man
      • arch wiki
      • understand how the system work to make a diagnose of the symptoms rather than just looking for the fast fix
    • what’s GNU?
      • general
        • when people say linux they refer to linux kernel + GNU. The latter is “the actual OS”
      • Story
        • UNIX was exclusive, so GNU was born to make it more accessible
      • core utilities like cd, ls, touch, etc
      • gcc - compiler
      • GPL based
