It’s literally Arch Linux but with an easy bundled installer and a couple of small tools you’ll forget about.
I am using it until the archinstall script gets easier for dual-boot, encrypted BTRFS configs.
I kinda wished the EndeavourOS team made efforts to improve archinstall and simply bundled their couple extra tools as that, extra tools for easier Arch Linux usage, instead of branding it all like a new distro.
