Nix package manager on Fedora Silverblue

Warning

Disable composefs or enable root.transient before install and use nix on Fedora Silverblue 42. Do not mix both. Use just one method. I prefer enabling root.transient.

• With composefs disabled

  sudo sed -i 's/,ro//' /etc/fstab
  
  sudo rpm-ostree kargs --append='ostree.prepare-root.composefs=0' --reboot

How to make a new rpm-ostree desktop variant in Fedora?

So you want to make a new rpm-ostree desktop variant in Fedora to join Silverblue, Kinoite and Sericea? Here are the steps that you should follow.

First, you should figure out what packages should be installed in your image. To do that, you can start from the base container image (https://quay.io/repository/fedora-ostree-desktops/base) and add packages from the comps group corresponding to your desktop in Fedora : https://pagure.io/fedora-comps

At this point, you should consider which apps are going to be shipped by default, included in the image, and which ones are going to be installed by default as Flatpaks.

Once you've got something working, reproduce that in https://pagure.io/workstation-ostree-config using the comps group and the filter and sync script. Look at other variants for example.

Linux (Manjaro [Arch]) on a Thinkpad P14s [T14] Gen2 with Intel

These are my installation-tricks and notes for running Linux on a 2021 Thinkpad P14s Gen2 with 11th gen Intel Core i7-1185G7. It should also be suitable for the Thinkpad T14 Gen2 with Intel as they are technically the same model.

Additionally you may find more AMD specific tips on the gist I've forked. I decided to keep this gist forked as I have used some of the tips they shared and because they inspired me to create my note in the first place.

Sadly there is no entry in the arch-wiki for Intel specific model, but some of the info from AMD one were useful for me. Other useful sources are mentioned in the document in their respective chapters.

Not everything in this doc may be 100% correct as I'm writing this note after having my PC set up and I might have forgotten some of the stuff. I will update it I ever decide to reinstall the OS on my PC.
