docs: update nydus repository URLs

thaJeztah · jsternberg · commit 281567c35483 · 2025-12-16T10:58:50.000-06:00
The repository was renamed to https://github.com/dragonflyoss/nydus, and while GitHub does provide redirects, their services have been a bit flaky recently so sometimes the redirects would fail. Signed-off-by: Sebastiaan van Stijn <github@gone.nl> (cherry picked from commit 8607e21)

 ## Nydus image formats
 
-Nydus is an OCI/Docker-compatible accelerated image format provided by the Dragonfly [image-service](https://github.com/dragonflyoss/image-service) project, which offers the ability to pull image data on-demand, without waiting for the entire image pull to complete and then start the container. It has been put in production usage and shown vast improvements to significantly reduce the overhead costs on time, network, disk IO of pulling image or starting container.

 Nydus image can be flexibly configured as a FUSE-based user-space filesystem or in-kernel [EROFS](https://www.kernel.org/doc/html/latest/filesystems/erofs.html) (from Linux kernel v5.16) with nydus daemon in user-space, integrating with VM-based container runtime like [KataContainers](https://katacontainers.io/) is much easier.

 ### Building Nydus with BuildKit

 ### Known limitations
 
-- The export of Nydus image and runtime (e.g. [docker](https://github.com/dragonflyoss/image-service/tree/master/contrib/docker-nydus-graphdriver), [containerd](https://github.com/containerd/nydus-snapshotter), etc.) is currently only supported on linux platform.

 - Nydus image layers cannot be mixed with other compression types in the same image, so the `force-compression=true` option must be enabled when exporting both Nydus and other compression types.
 - Specifying a Nydus image as a base image in a Dockerfile is supported, but it does not currently support lazy pulling.
 - Since exported Nydus image will always have one more metadata layer than images in other compression types, Nydus image cannot be exported/imported as cache.
