I like the idea of DietPi (and I have a couple of Orange Pis running it) but I want to run the install off an HDD. Not just user data - the whole thing (and preferably use an old 256Mb SD Card for the boot stuff).
Seems I cannot which is a shame. Oh and BTW, when I ask it not to move user data to the HDD, I really meant it (but it seemed to do it anyway).
I have used https://github.com/debian-pi/raspbian-ua-netinst in the past and that ran like a charm. Perhaps a combination of the 2? Net install DietPi to an HDD? This sadly does not seem current enough for me so back to Raspbian Lite and a manual move to the HDD.
