Some packages won't install properly without a reboot. Chocolatey never reboots the PC. from my recollection there was a return code that advises that a reboot is required @ferventcoder can probably confirm?.

This resource would benefit if we can add a variable "SupressReboot" into the cChocoPackageInstall which if it's FALSE the DSC config will set the global variable for a reboot required.. DSC would then either reboot or not reboot based on your individual configuration.
