Festa della Repubblica
I can read Italian. I checked out the support forums, and the posts typically had just a couple of participants. Liam's point about the distro probably being niche seems to be accurate.
OpenMamba is an independent Italian distribution which uses Fedora's packaging tools and offers a choice of KDE Plasma or LXQt. The independent desktop Linux distro has been quietly slithering along since about 2009. Like the snake whose name it shares, it's very green-hued, but it doesn't bite. In recent years, it's a one man …
Quite so...it is a big hurdle going off-piste like this, if you will forgive the mixed metaphor. If you Google 'how do I do xyz in Debian/Fedora/whatever' you will most likely get a reply, this... probably not so much. A distro for the adventurous, methinks, not that there's anything wrong with that.
Reminds me a bit of PCLinuxOS. Independent distro, rolling release, (mostly) a one-man project, uses RPM packages, focus on KDE Plasma. The main difference seems to be that PCLinuxOS doesn't use systemd and OpenMamba does. But to be honest, I wouldn't use a rolling release distro that doesn't have an automatic snapshot system with Grub integration like OpenSuse does with Snapper. I want to have that peace of mind.
