MOTD Chef Status Cookbook

Maintainer: OIT Systems Engineering (ua-oit-se@alaska.edu)

Purpose

This cookbook configures Message of the Day to display system information and Chef status.

  • Standard OS, machine, and hostname information
  • Chef node name, run success status, last run timing

It also clears some distro-standard MOTD fragments.

MOTD is dynamic on every supported distro. When it is available and works on the platform, update-motd is used. Otherwise profile is used as a fallback.

The MOTD message is reasonably standard across platforms. This cookbook does not configure SSH, so any login message will remain. Effort has been made to remove fragments from standard distributions and cloud-provider fragments, but is it infeasible to remove every possible fragment while respecting attributes that govern their removal.
