## Bootstrap a windows node to sev1 chef
# Requirements:
#   - A validator key must be present on the target node at `c:/cinc/validator.pem`
#     Your key can be found at by going to your vault /client/<your_client_id>/secret/chef/chef-server/validator"

# Usage:
# Copy this script to your target and run it like so:

This is one of those "I have to do this occasionally and can never remember how" things - mounting an ISO in macOS, especially Linux ISOs.

macOS has a few things that are stupid. Trying to mount a .iso file directly using normal means ends in failure:

hdiutil: mount failed - no mountable file systems

It's completely doable, unlike other image formats (.img, .dmg, etc), just takes a bit more effort.
