Linux distributions

Having many flavors makes some lovely hot garbage…

ubuntu

  • debian based
  • snaps and apt for packages
  • zfs by default
  • aws EKS for baremetal
    • EKS auto mode
    • EKS-D is the distro that can be self hosted through snap, baremetal, kubeadm etc
    • preinstalled components
      • metallb for load balancer
      • Cilium CNI for networking
      • Flux for gitops
      • eksctl for control
    • same pod and node limit at kubernetes (5000 nodes, 110 pods per node, 150000 total pods, 300000 total containers)
    • build own ova https://github.com/aws/eks-distro-build-tooling
    • can run locally with containers (based on amazon linux 2)
      • requires docker with cgroupsv1

arch/manjaro

  • arch based
  • pamac and pacman for packages
  • mkinitcpio for initramfs
    • MODULES="nvidia nvidia_modeset nvidia_uvm nvidia_drm"
    • add zfs to hooks
  • blacklist nouveau and options nvidia_drm modeset=1 in /etc/modprobe.d/mwhd-gpu.conf for nvidia gpu direct render management
  • pacman -U *.zst to install local
  • makepkg to build
  • pacman -Syu to update

RHEL

  • dracut for initraramfs
  • yum/dnf for package managers
  • fedora uses btrfs
  • killed centos
    • replaced by rocky/alma

gentoo

  • portage for packages
    • use flags for config
    • overlays for external repos
    • can use binaries but usually source only
