Netavark is a Rust-based tool for configuring networking for Linux containers that serves as a replacement for CNI plugins (containernetworking-plugins on Fedora). Aardvark-dns is now the authoritative DNS server for container records. Along with the new stack comes distro packaging changes along with repository availability changes for Fedora 35.
For Fedora users
Podman v4 is available as an official Fedora package on Fedora 36 and Rawhide. Both Netavark and Aardvark-dns are available as official Fedora packages on Fedora 35 and newer versions and form the default network stack for new installations of Podman 4.0.
