Note that as of this date (Jan 25, 2023) I have verified that this install script works with ReadyNASOS6.10.8 on both Intel and ARM systems. The installed version isn't the latest. It's 1.4.0, while 1.8.9 is current, but anything newer seems to have broken dependencies. But it's still a lot more up to date than the nt3 one. There isn't normally any ongoing configuration updating required, so you may never need to go into SSH to control it again. ZeroTier operation does resume after a power cycle.
No, that should have worked. The system on which I recently installed it does not have KernelPlus, so that could be a difference. It was actually a legacy NAS converted to OS6, but that shouldn't make a difference. You can download the 1.4.0 .deb and try to install that.
The new version contains only a single feature: A new board setup mode in which you can place black or white stones in any order and combination to set up the initial board before you begin to play moves. This feature is a continuation of the work begun in version 1.4.0, where I added support for loading and saving .sgf files that contain stone and/or player setup nodes.
Little Go 1.4.0 has been published on January 15 2019 on the App Store, followed-up two days later by the 1.4.1 update that contained a high-prio bugfix. Version 1.4.0 is a maintenance and bugfix release that mainly focuses on updating the project to the newest development environment, Xcode 10.1 and iOS 12.1 SDK. 59ce067264
