Pinchflat isn't being maintained and has a few annoying bugs already.
Someone was working on a "community maintained" fork that had a bunch of fixes and new features and were also working on a hard fork with even more features but then last week they abruptly overwrote the history of the repo so there's nothing but a script to migrate back to the main pinchflat. They also deleted all the packages which means docker pull now errors if you have their version. Thankfully someone had a fork of that one saved but the person who saved the fork doesn't have the programming skills to continue development so we're back to it not being maintained.
