Rootless Podman (and rootless Docker for that matter) is not difficult to set up automatically. There is a little complexity involved, namely in configuring subuid and subgid mappings, but not much.

That said, I think Arch Linux itself has a culture that values the wrong kind of simplicity (implementation simplicity) that perversely leads to a failure to adequately grapple with inherent complexity. This leads to brittle implementations, "buyer beware" norms, "you should have run the notes", "this command should never be used", etc. Omarchy inherits all of that from Arch. It also, it seems, carried its own perverse notion of "simplicity".

I was not referring to the setup complexity. Setup is performed just once. I was referring to the runtime complexity that comes naturally from having to take into account non-root user permissions and lack thereof. These peculiarities are quite a low bar, but they are still a non-trivial hurdle in the way of devex.

I am a fedora/opensuse user and happily use podman with selinux.
