I maintain an immutable (OSTree) Fedora XFCE variant called Vauxite. There are currently no installer images, but Vauxite may be installed from an existing OSTree-based system like Fedora Silverblue or Fedora IoT:
Add my server URL as a new remote:
sudo ostree remote add --no-gpg-verify vauxite https://ostree.hyperreal.coffee
Pin the current tree in case something breaks during or after the rebase:
sudo ostree admin pin 0
Rebase the tree to Vauxite
rpm-ostree rebase vauxite:vauxite/f36/x86_64/base
In case of failure or breakage, rollback to the previous commit:
The Vauxite tree is rebuilt every Tuesday and Saturday to keep up with upstream security updates.
I've submitted a PR to the workstation-ostree-config repo on pagure.io, which is the upstream for immutable Fedora variants.
