[09:23] <ogra_> blahdeblah, theer should be debian based images for the beaglebone black ... grab one, write it to SD, fish /lib/modules and /lib/firmware out of the rootfs, format the rootfs partiton, unpack ubuntu core into it and copy the two dirs in place .... that should be enough to get you started
[10:30] <blahdeblah> ogra_: Thanks - any idea about kernel?  Ubuntu core doesn't seem to come with one.
[10:30] <ogra_> just use the debian one, that should be fine
[10:31] <ogra_> (you can indeed also use an ubuntu kernel or even upgrade to one later, but setting up bootloader and kernel is much more complex than just replacing the rootfs)
