Anyone made a DIY immutable distro? in c/linux@lemmy.ml
[–] jlsalvador@lemmy.ml 4 points 1 week ago* (last edited 1 week ago) (1 children)

Hi!

I made my own inmutable distro using buildroot (https://buildroot.org): https://simplek8s.org

This distro is just an AIO kernel image that will bootstrap everything in RAM. You can mount additional devices for data persistence (for example you can mount your storage in /var).

Forgejo is now copyleft, just like Git in c/opensource@lemmy.ml

TLDR; from MIT to GPL.

Disappointing and poorly crafted ending. There are scenes from the trailer that doesn't include in the final game.

Question: What is Linux misinformation? in c/linux@lemmy.ml

For example, when someone ask for a command to list files, and another one reply with a command that removes everything.

Getting PSVR2 working on PC isn't as easy as it should be in c/gaming@beehaw.org

TLDR; the reviewer is upset because the PSVR2-PC adapter doesn't come with a Display Port cable, and his Bluetooth adapter is not compatible. So he can't review the unit on time until he receive both items. 🤷

It's illegal in Europe to have an opt-out checked by default, must be an opt-in unchecked by default. This is one of the reason that Microsoft has always troubles in Europe about privacy and opt-out services.

Hahaha. Common problem with multiscreen with different resolutions. Your laptop screen is below and left of your main display, and X11 renders this black "virtual screen".

There are multiple solutions:

a) Set your screen resolution and position through KDE Plasma SystemSettings and push the button "apply to SDDM configuration" (I think Plasma 6.0 removed this option, try to find it in the SystemSettings KCM SDDM section).

b) The another solution is the old one. Create a file into /etc/X11/xorg.conf/display.conf with the proper values of position and resolution. Search in a wiki about examples (archlinux wiki?).

c) There is a third one that I used few years ago. SDDM allows you run any command after the screen initialization. So you can exec your xrand command here. Search about /etc/sddm.conf

KDE Plasma 6 Tip: How to remove watermark preview banner from desktop (lemmy.ml)
 

Hello!

Do you hate the watermark preview banner?

Add the text HideDesktopPreviewBanner=true just after [General] in the file ~/.config/kdeglobals. You will have something as the following:

[General]
HideDesktopPreviewBanner=true

Better for OLEDs displays, stylish, auto-suspend all-blacks displays, etc.

Caution disabling mitigations. Only enable on air-gap devices (devices without any connection, airplane mode).

Ratatan Kickstarter campaign launched in c/gaming@beehaw.org

A full price release for the first milestone, and because it is a Kickstarter, without any guarantee. I'm sure that the Patapon fans will be happy, at least.

Asking for advice: Releasing a custom rolling immutable simple distro for Kubernetes (lemmy.ml)
submitted 1 year ago* (last edited 1 year ago) by jlsalvador@lemmy.ml to c/kubernetes@lemmy.ml

Hello world!

I want to release to internet my custom immutable rolling-release extreme-simple Linux distribution for Kubernetes deployments.

I was using this distribution for about the last 6 years on production environments (currently used by a few startups and two country's public services). I really think that it could be stable enough to be public published to internet before 2024.

I'm asking for advice before the public release, as licensing, community building, etc.

A few specs about the distribution:

  • Rolling release. Just one file (currently less than ~40Mb) that can be bootable from BIOS or UEFI (+secure boot) environments. You can replace this file by the next release or use the included toolkit to upgrade the distribution (reboot/kexec it). Mostly automated distribution releases by each third-party releases (Linux, Systemd, Containerd, KubeAdm, etc).

  • HTTP setup. The initial setup could be configured with a YAML file written anywhere in a FAT32 partition or through a local website installer. You can install the distribution or configure KubeAdm (control-plane & worker) from the terminal or the local website.

  • Simple, KISS. Everything must be simple for the user, this must be the most important aspect for the distribution. Just upstream software to run a production ready Kubernetes cluster.

  • No money-driven. This distribution must be public, and it must allow to be forked at any time by anyone.

A bit of background:

I was using CoreOS before Redhat bought them. I like the immutable distro and A/B release aspect of the CoreOS distribution. After the Redhat acquisition, the CoreOS distribution was over-bloated. I switched to use my own distribution, built with Buildroot. A few years later, I setup the most basic framework to create a Kubernetes cluster without any headache. It's mostly automated (bots checking for new third-party releases as Linux, Systemd, Containerd, KubeAdm, etc; building, testing & signing each release). I already know that building a distribution is too expensive, because of that I programmed few bots that made this job for me. Now days, I only improve the toolkits, and approve the Git requests from thats bots.

Thank you for your time!
