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:
- the Linux Kernel
- GRUB or another bootloader
- one or more file systems (gotta work with files somehow, right?)
- one or more Shells (the terminal - bash, zsh, etc…)
- a Desktop Environment (the GUI, if included, like KDE or Gnome - does this include X11 or Wayland or are those separate from the DE?)
- a bunch of Default applications and daemons (is this where systemd fits int? I know about the GNU tools, SAMBA, CUPS, etc…)
- 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!
Fun fact, the init process can be anything, even /bin/bash or a shell script. But if it ends or dies so does the system, and of course you want extra features like multiuser capability, better interface etc. So it’s typically a more complex system like you said, that starts a bunch of other things. But you can still see the init process with PID 1 there in the process list. 😊
