The k3s update script filters the assets of a corresponding release for airgap images archives and provides these as passthru attributes of the k3s derivation. We use zstd archives, as these offer the best compression ratios and decompression speed. Furthermore, the `airgapImages` passthru provides the images archive that matches the host platform architecture, however, this only works for aarch64 and x86_64. In addition, a txt file listing all container images of a release is made available via a passthru attribute. The airgap images archives can be combined nicely with the `services.k3s.images` option, e.g. to pre-provision k3s nodes for environments without Internet connectivity.
