Hi all - I am learning about Linux and want to see if my understanding is correct on this - the list of major parts of any distro:

  1. the Linux Kernel
  2. GRUB or another bootloader
  3. one or more file systems (gotta work with files somehow, right?)
  4. one or more Shells (the terminal - bash, zsh, etc…)
  5. a Desktop Environment (the GUI, if included, like KDE or Gnome - does this include X11 or Wayland or are those separate from the DE?)
  6. a bunch of Default applications and daemons (is this where systemd fits int? I know about the GNU tools, SAMBA, CUPS, etc…)
  7. a Package Manager (apt, pacman, etc…)

Am I forgetting anything at this 50,000 foot level? I know there are lots of other things we can add, but what are the most important things that ALL Linux distributions include?

Thanks!

    I would say, that from most important to least important components are:

    1. kernel
    2. init system (systemd, openrc, runit…)
    3. C library (glibc, musl)
    4. filesystem
    5. coreutils
    6. shell
    7. bootloader
    8. package manager
    9. x11/Wayland (if any)
    10. sound system (if any)
    11. WM (if any)
    12. DE (if any)

      One thing I don’t know: if C is a compiled language already, what exactly does the C library do?

        Most C binaries usually do not contain everything needed for their execution. It would make them too platform-specific. What most c programs do is that they use standard c library from platform for low-level things and communication with the system like memory allocation or stdin/stdout things, for example.
