Google's mysterious operating system, dubbed Fuchsia, has been in the works for more than a year now with very few details about the OS made public. According to a new report from Chrome Unboxed, we have learned that Google has released documentation to allow developers to load Fuchsia onto the company's Pixelbook. The Verge reports: This isn't your typical developer operating system, and you'll need two machines to host and target a Pixelbook to load the OS. It's very much a work in progress, with early hints at a user interface and functions. It's still interesting that Google has chosen its own Pixelbook to experiment with, though. Fuchsia has mostly been linked to embedded systems like wearables and Internet of Things devices in the past, but testing was expanded to Intel's NUC and Acer's Switch Alpha 12 Chromebooks. Fuchsia has been created from the Google-built Zircon microkernel, and not the typical Linux kernels that hold Android and Chrome OS together. It's not immediately clear exactly why Google is building a new operating system, nor what devices it will run on. As testing spreads to more Chromebooks, some are now speculating this could be a successor to the "Andromeda" project that never materialized.
