@george said in merge back to armbian source:

my main focus is on Ubuntu Debian

• Armbian userspace is lean, clean but 100% Debian/Ubuntu compatible
• Armbian Linux is available as Debian and Ubuntu based images, compiled from scratch
• Many stock Debian bugs are fixed on the way, “better than original :)”

... and more.
