Been successful using Kairos to build and deploy an immutable RHEL9 to environments without internet access. Appreciate the flexibility to work with different distros and the maintainers provide great support.
RH also provides immutable OSes (Kairo uses some of their stuff) via Fedora Atomic and Fedora CoreOS, so for a single RHEL-like immutable instance, i'd just go CoreOS or Kinoite
The main reasons to use Kairo are perhaps more around the P2P mesh, using Cloudinit, deb vs rpm etc.
