wtf is distribution?

This repository is a fork of ROCKNIX, described here as adding support for the GKD Pixel 2 handheld gaming device. ROCKNIX itself is an immutable Linux distribution built specifically for handheld gaming devices, made by a small community of enthusiasts who wanted an operating system with the features they personally needed for retro and portable gaming. The README describes a wide set of features carried over from ROCKNIX. It includes cross device local and remote network play for multiplayer gaming, in-game touch support on devices that have touchscreens, and controls to balance battery life against performance. It supports playing music and video files, Bluetooth audio and controller connections, and HDMI or USB audio and video output. For keeping game saves and files synced, it includes Syncthing and rclone for device to device and device to cloud syncing, plus VPN support through Wireguard, Tailscale, and ZeroTier. It also has built in support for scraping game metadata and for retroachievements, a system that tracks in game accomplishments. Since this is a Makefile based project, building it likely involves compiling the operating system image from source using build scripts rather than installing a typical application, though the specific build steps for this fork are not detailed in the material provided. On licensing, ROCKNIX itself is a fork of another project called JELOS, and credits that team. The distribution's original scripts are licensed under GNU GPL Version 2, while other bundled software keeps its own original license. The broader documentation content is shared under terms that allow copying and adapting the material with attribution, but not for commercial use, and any remixed version must be shared under the same terms. The community around ROCKNIX gathers on Discord for support and discussion, and the project credits contributors from other open source handheld projects like CoreELEC, LibreELEC, and JELOS.
