Marty Oehme cf00dabeb0 Allow Choice of package group presets when provisioning
Choice is presented at beginning of provisioning and can choose from 3 different package groups (desktop, laptop, headless) with emphasis on different deployment functionality. Additional packages to run installation against can also be passed in as command option with -f "/path/to/packages.csv /path/to/more.csv" which will get installed alongside the selected package group. When choosing -F the packages will get installed as the only packages instead.
