# Title:        Package Installer
# Author:       Hak5Darren
# Version:      1.0
#
# Description:	This payload will install the specified package using opkg.
# Use this to provision your Shark Jack for payloads with dependencies.
# Set PACKAGE_TO_INSTALL to the package you wish to install - for example
# PACKAGE_TO_INSTALL="nano" will install the best text editor on Earth ;)
# For a list of available packages, set LIST_PACKAGES to 1 - the results
# will be saved to a log file in the loot directory. Requires Internet.
#
# LED SETUP (Magenta)... Setting logs and waiting for IP address from DHCP
# LED FAIL (Red Slow Blink)... Failed to update opkg or install package
# LED SPECIAL (Cyan Blink)... Saving package list to log file
# LED FINISH (Green Fast Blink to Solid)... Package install or list successful
