The last time that I wrote about non-Raspbian Linux on the Raspberry Pi, I overlooked Manjaro because I thought their ARM project had been shut down. This error was pointed out to me in a comment to that post, and I subsequently found the Manjaro ARM re-launch announcement from last spring.
It now exists as a project with its own web page, a small group of dedicated developers, and a focus on the Raspberry Pi 3 and Odroid C2 SBCs, and the Pinebook laptop. When I saw the announcement of Manjaro-ARM 18.12.1 on the Manjaro News page, I decided it was time to get back to this, so here we go!
First, a few words about supported devices. I'm not sure that I really understand everything about this; the release announcement specifically mentions the Pi 3, Odroid C2 and Pinebook laptop, with LXQt and KDE desktops, and a "minimal" version which I assume is CLI-only for the Pi and Odroid. However, it doesn't specifically mention the Raspberry Pi 2, and although there is not a new image for the Pi 2, it does say that "Old images should just keep on rolling". I will just give that a try before I finish this post.
