Liri OS

Liri OS is available as an immutable tree with reliable updates and easy rollbacks.
Right now the live image installs a traditional, package-based system, but if you are running Fedora Silverblue you can try the rpm-ostree based version of Liri OS today.
First of all add the remote and pull the latest version:

ref=lirios/unstable/x86_64/desktop
ostree remote add --no-gpg-verify liri https://repo.liri.io/ostree/repo/
ostree pull liri:$ref
ostree admin os-init lirios
ostree admin deploy --os=lirios --karg-proc-cmdline liri:$ref
checksum=$(ostree rev-parse $ref)
for i in /etc/passwd /etc/group /etc/shadow /etc/fstab \
         /etc/default/grub /etc/locale.conf \
         /etc/ostree/remotes.d/liri.conf; do
    cp $i /ostree/deploy/lirios/deploy/${checksum}.0/$i
done

If you have a separate /home mount point, you'll need to change that fstab copy to refer to /var/home.
If you don't have a separate /home mount point, then you need to make sure that a symlink will be created:

echo 'L /var/home - - - - ../sysroot/home' > /ostree/deploy/lirios/deploy/${checksum}.0/etc/tmpfiles.d/00rpm-ostree.conf

and copy your home directory from the fedora-workstation deployment:

cp -a /sysroot/ostree/deploy/fedora-workstation/var/home/<USERNAME> /sysroot/ostree/deploy/lirios/var/home

(Replace with your actual username)
