Obarun 2021.07.26 Review
Obarun is a derivative of Arch Linux with systemd replaced by the s6 init software. The distribution is available in two flavours, Minimal and with JWM as the default window manager. The Minimal edition is an 837MB download while the JWM edition is 1.3GB in size. I chose to download the JWM edition for x86_64 computers.
