Developer Arne Exton announced earlier a new version of his ExTiX GNU/Linux distribution, dubbed ???The Ultimate Linux System???, which is based on the upcoming Ubuntu 20.04 LTS (Focal Fossa) operating system, but uses KDE Plasma as default desktop environment and Calamares as default installer. ExTiX 20.2 is also one of the first GNU/Linux distributions to adopt the recently released Linux 5.5 kernel series, which brings a new Airtime Queue Limits (AQL) feature, SMB multichannel support, SMB rootfs, a new unit testing framework called kunit, Btrfs RAID1 with 3- and 4- copies, and three new Btrfs checksums.
