kernel-ark VS k3os

EDIT: Actually, I tested this just now by setting module.sig_enforce=1 in the kernel cmdline and it doesn't work. It turns out Fedora/Ubuntu/etc ship this custom patch in the kernel that explicitly allows using platform (secure boot) keys for verifying kernel modules: https://gitlab.com/cki-project/kernel-ark/-/commit/07db43366d560153fd1d418cfebe2370fb20697e. The patch is not in the upstream kernel yet, so Arch doesn't have it.

kernel patched with cherry-picked zen patches (also used in TKG kernel on Arch https://github.com/Frogging-Family/linux-tkg/blob/master/linux-tkg-patches/6.1/0003-glitched-base.patch) kernel patched with OpenRGB (https://gitlab.com/CalcProgrammer1/OpenRGB/-/wikis/OpenRGB-Kernel-Patch) kernel patched to enable amdgpu for pre-polaris cards by default instead of radeon kernel patched with steam deck support kernel patched with microsoft surface support (https://github.com/linux-surface/linux-surface/tree/master/patches/6.1) kernel patched with asus-linux patches for better asus laptop compatibility. (https://gitlab.com/asus-linux) kernel patched with simpledrm fix/workaround for nvidia (see: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1788 ) kernel patched with ACS override IOMMU patch for better vfio iommu group control (https://aur.archlinux.org/cgit/aur.git/tree/add-acs-overrides.patch?h=linux-vfio) kernel patched with Lenovo Legion Linux support (https://github.com/johnfanv2/LenovoLegionLinux) kernel patched with customizable USB polling rate support (https://github.com/KarsMulder/Linux-Pollrate-Patch + https://github.com/GloriousEggroll/Linux-Pollrate-Patch) kernel configured with ashmem, binder, and android support for Waydroid QSG_RENDER_LOOP=”basic” set for nvidia cards — fixes nouveau Wayland freezes. The nvidia proprietary driver sets this anyway after installation. This fixes the issue of KDE Wayland often times freezing on first login before nvidia proprietary drivers are installed. latest mesa release version provided for AMD/Intel desktop/GL drivers, mesa-git vulkan drivers provided for latest vulkan fixes/updates, built and updated regularly (every few weeks to a month on average) glibc patched with clone3 disabled (fixes CEF compatibility in applications using outdated CEF such as Discord, Steam beta) glibc patched with broken commits reverted to allow EasyAntiCheat to work for Rogue Company dnf max parallel downloads increased to 6 gst-editing-services disabled — causes WINE to hang when creating new prefixes lspci symlink from /usr/sbin/lspci to /usr/bin/lspci for Dying Light: https://www.gamingonlinux.com/forum/topic/2766/post_id=17381 ‘nobara-controller-config’ package provided for easy installation of xone and xpadneo drivers and firmware. gnome variable refresh rate patches added for mutter: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1154 gnome mutter check-alive-timeout increased from 5 seconds to 30 seconds. This is the amount of time gnome waits before trying to determine if an application is not responding. At 5 seconds it almost immediately triggers for league of legends (and some other applications) if those applications are still in the loading phase. We feel 30 seconds is a much more reasonable wait time. gnome mutter patched with x11 fractional scaling: https://salsa.debian.org/gnome-team/mutter/-/raw/ubuntu/master/debian/patches/ubuntu/x11-Add-support-for-fractional-scaling-using-Randr.patch gnome mutter wayland and x11 fractional scaling enabled by default: https://wiki.archlinux.org/title/HiDPI#Fractional_scaling gnome shell patched with https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2358 to allow gnome-extension-manager to auto-update without needing gnome-extension-app installed. (They both function the same but gnome-extension-manager allows management of extensions without a browser). gamescope version regularly updated goverlay version regularly updated mangohud version regularly updated vkbasalt version regularly updated vm.max_map_count = 16777216 set by default for Star Citizen xwayland patched with fix for locked fps on some systems: https://build.opensuse.org/package/view_file/home:hwsnemo:xwayland/xwayland/xwayland-vsync.diff?expand=1 supergfxctl and gnome extension + kde plasmoid enabled for laptops. Vendor agnostic and works with any combination of intel/amd/nvidia gpus.

Do do indeed, but they also curate their own downstream patches for the kernel and system libs. Their kernel repo is here https://gitlab.com/cki-project/kernel-ark. You have to specifically opt in to vanilla mainline builds of the kernel via https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories.

I still don't forgive SUSE for buying Rancher and then unceremoniously killing k3os. They just left the website up and everything, made no announcement, made no attempt to help the community take over, just left the Github repo to rot: https://k3os.io/

Hard to have confidence in SUSE's commitment to another open source operating system side project after that. SUSE's announcement at the time:

Like SUSE, Rancher is 100% open source and equally as passionate as SUSE about true open source innovation, community empowerment, and customer success. SUSE and Rancher share the same goal – happy and satisfied customers.

k3os is no longer supported by Rancher: https://github.com/rancher/k3os/issues/846 I've been keeping mine up to date with https://github.com/BlueKrypto/k3os

I (still) run k3os, but it's dead since SUSE bought rancher. (see https://github.com/rancher/k3os/issues/846)

I'm personally fond of https://k3os.io for my small to medium hobby and professional clusters. It comes with a lot the bells and whistles, but is also pretty minimum and just scales easily.

I really liked K3OS, but I feel like Rancher is no longer supporting it. The last commit on the k3os repo is from April, and before those three commits, November of last year. When Rancher decided to move their HCI offering, Harvester, over to RancherOS V2 being based on cOS toolkit/OpenSuse, I don't have high hopes that K3OS will be maintained.

I run k3os on an old laptop with a broken screen.
