I tinker a lot, mostly desktop Ubuntu, but venture also into RPi; Fedora; Kali; Bodhi… I got a recommendation to try out start9 in Bedford in the after hours, this year, when Umbrel was discussed. So this year, I would like to build a stack of software tools, that will require a lot of disk… and know it seems to support only one hdd, on release 0.3.4. Maybe that has changed. So far I like what I see.
