Because dear Sir ,I make images for the amateur radio community
loaded
with amateur repeater & gateway software with a support yum repository.
When Fedora gets an image equivalent in functionality to the Ubuntu BBB
image, then I shall shape it from there.
You don't mention what that functionality is, I've never used Ubuntu
nor do I have the time or interest in doing so, so you need to
actually be explicit in the actual features that you're interested in.
