#!./bin/knife exec

# A knife exec script to change chef node's name, preserving all the attributes.
#
# Usage: knife exec rename-node.rb old-name new-name
#
# Script retrieves the Node object, changes its 'name' attribute,
# creates new Node object with updated name and rest of attributes
# untouched. Then it deletes old Node and Client objects from
# database, and logs into the server to update it:

# Chef resources describing how to set up package repository server,
# simplified fromactual cookbook (not open sourced yet). Sets up apt
# repository in /srv/apt directory, with system user "apt-repo". Packages
# are GPG-signed to prevent apt-get from complaining on every install.
# 
# Directory /srv/apt should be reachable to clients via http or other
# means. This is left as an exercise for the reader.

# Trace 'print' statement calls cluttering your test suite output.
#
# It is not that simple to track 'print' statement in Python 2.x - it
# cannot be monkey-patched itself, because it's not a function. So we
# override sys.stdout and check the backtrace when stdout is written
# to.
#
# The overload happens only if TRACE_PRINT environment variable is
# set. By default, only the offending file name and line number is
# printed; if TRACE_PRINT environment variable is set to 'traceback',
