NORD

This is the Github repository for NORD, a minimalist computer operating system suitable as a base for server, desktop, or embedded systems. It is built to start fast and run light. It uses the Linux kernel and Linux-related packages.

Keeping Linux Simple

NORD is a Linux system that tries hard to not be yet another distro.
It uses two different build schemes, both of which ride on top of the standard recipe. NORD uses source archives aquired directly from the individual package authors and maintainers. The result is a system with no dependency on any central distributor.

While NORD uses the Linux kernel, it is more about Unix than Linux.

Standard Recipe

NORD follows the standard recipe for building internet sourced packages.

# get the source, keep your copy indefinitely
# explode the source
./configure
make
make install

On top of that are two build schemes.

  • CSCRATCH builds the core of NORD into a bootable root filesystem using an existing host platform (not necessarily NORD)
  • Chicory (the /usr/opt scheme) builds non-core packages (not exclusively for NORD) as relocatable, possibly shareable components (similar to IBM /usr/lpp or Sun /opt/SUNW)

Between these two is a solid base with a lot of flexibility.

Hardware Platforms

Ideally, NORD can run on any hardware supported by Linux. The following work now:

  • s390
  • i386
  • ppc, except for the bootstrap
  • arm, except for the bootstrap, borrows host runtime
  • sparc, except for the bootstrap

Platforms listed here as "except for the bootstrap" run in 'chroot'. Those which are "except for the runtime" borrow the runtime of a distributor-provided host.

Above are the 32-bit variants of bi-modal architectures. The 64-bit counterparts have been underway (slowly) for some time.

ZNETBOOT

When hosted on z/VM, NORD is most easily installed via ZNETBOOT.

ZNETBOOT itself is just a CMS-based web-oriented loader and can be used to bootstrap any Linux distribution.
Try it!

See the ZNETBOOT project on Github, or download from http://www.casita.net/pub/znetboot/znetboot.vmarc or http://www.casita.net/pub/znetboot/znetboot.tar.gz

Use the nord.znetboot config file included. Tailor it to your specific configuration, then run the command

znetboot nord
