I've recently learned how to modify Linux distros. Now I want to be able to share my modified versions with others. I want to do so in a legally correct way. I see a set of related questions, I put them all here, if they are better be asked separately, please comment about it below.
I've tried to read what web search and links provided, namely: Custom Linux distro Copyright and license notices, https://unix.stackexchange.com/questions/308476/can-you-legally-sell-modified-versions-of-linux-distros, https://askubuntu.com/questions/720735/can-one-modify-ubuntu-and-publish-it-as-their-own-linux-distro, https://www.reddit.com/r/linux4noobs/comments/kg6int/what_is_the_difference_between_a_linux/
I see a problem on a general level as: I got intellectual property, it is a set of files that represent many software, art works and names. How am I supposed to find out which parts are covered by which licenses? When I start a distro (Linux Mint, Ubuntu, Fedora, Arch) I don't recall a need to read and agree to a legal stuff unlike for e.g. Microsoft Windows.
For software it is mostly GPL and that is covered in the found links to large extent.
- Can I leave links to Fedora, Ubuntu repositories or do I need to provide another way to access source code? I've read advice to include all source, but obviously just leaving links to repos is easier. I see Mint distro uses Ubuntu repos, but maybe they got a "license" to do that.
Icons, wallpapers, etc. I've searched the drive for
license and found in
/usr/share/common-licenses "CC0 1.0 Universal" (which is AFAIK public domain) and some "Artistic License".
- How to find out which works are public, which are not?
Names: "Fedora", "Mint".
- Do I understand correctly that a flavour need approval for distribution from original distro distributor (that approval for some distros may be granted for all in advance, what distros allow that?)
- If I remove original distro name from "my distro", then I'm on a safe side, correct?
Please cover any other issues I have not identified yet.
