Fedora Project Considering "Stateless Linux"

Posted by timothy on from the man-without-a-country dept.

Havoc Pennington writes "Red Hat developers have been working on a generic framework covering all cases of sharing a single operating system install between multiple physical or virtual computers. This covers mounting the root filesystem diskless, keeping a read-only copy of it cached on a local disk, or storing it on a live CD, among other cases. Because OS configuration state is shared rather than local, the project is called 'stateless Linux.' The post to fedora-devel-list is here, and a PDF overview is here."

  1. Like Clusters by deadline · · Score: 5, Interesting

    This is similar to what clusters try and do. It is important to maintain the same OS state on all nodes. Take a look at Rocks Clusters. Rocks will push the same OS image out to the nodes of the cluster. There is no reason the cluster nodes could not be workstations on a desk.

    If you'd bother to read the white paper or howto (sure, I'm new here) you'd have read that this is more than NFS mounted roots.

    It's a framework for managing the servers, cached operation, integrated authentication etc. You can use this framework to manage roaming devices like laptops, allowing automatic install images, etc. etc.

    An NFS solution requires network connectivity the whole time, this doesn't.

    It's actually a lot closer to Solaris autoclients.
