Running a Linux distribution on Arm-based single-board computers (SBCs)
is still not as easy as on x86 systems because many Arm devices require a
vendor-supplied kernel, a patched bootloader, and other device-specific
components. One distribution that addresses this problem is Armbian, which offers Debian- and
Ubuntu-based distributions for
many devices. The headline feature in the recent release, Armbian
23.05, which came at the end of May, is a major rework of the build
framework that has been made faster and more reliable after three years of
development.
