VM friends -- Here's something I hope to mention on the Linux/390 discussion, but thought I should share it here first because it is inspired by z/VM ... and Mother.
NORD is a Linux build intended for embedded use (eg: as a service virtual machine, a rescue system, or any utility Linux). I was advised to share about it with the VM community first. NORD is, in fact, heavily inspired by VM. The whole design is based on things that are commonplace in VM. For example, just as we can replace CP and CMS without altering user content or (most) third party and add-on software, so it is with NORD. You swap out the core of the op sys ... instant upgrade. Oh, and your old disks are still there if you need to fall back. I just got burned by a Linux upgrade. It wasn't one of the major players in mainframe Linux, so I'm not picking on Mark or Brad or Shawn or any of those guys. I have seen upgrades work, but not the way most "distributed" systems do them (and certainly not the way upgrades are done with Linux). I'll send a second note with details. -- R; <><
