Since you are going to distribute Debian to users, and Debian includes a lot of copyleft-licensed software, you might be interested in this guide to GPL license compliance: http://compliance.guide/ This section offers an example of a product that meets the GPL requirements: http://compliance.guide/pristine Some more background on copyleft is available here: https://copyleft.org/ > Change the log screen during booting and display our logo This is perfectly acceptable to do. If you intend to also show the Debian logo, please note our trademark policy: https://www.debian.org/trademark > Run our custom software (written in Python & C) instead of OS desktop > environment If appropriate, I would encourage you to release this under a Free Software license and have your developers package it for Debian. > Do I need to purchase any license for my product from Debian?
