IN BRIEF
Openmamba is competent enough, stable and even comes with Raspberry Pi-optimised versions. However, it claims to be neither derivative nor dependent on other distros doesn’t quite feel right. The distro is maintained by one person, so perhaps it’s a little unfair to expect a complete ground-upwards effort with this level of polish.
