content: I have used Cyanogen in the past, and I am vaguely aware of Lineage, but how easy is it to put on a modern phone? Seems like it's been getting more and more difficult to get a phone that will let you install custom OSs. Honestly, when it comes to phones I really don't know a lot about the underlying structure. Most of that is just that I've never really done it, but I had a hell of a time figuring out how to install Cyanogen even back when it was simple to root a phone.
