Thanks so much for this explanation, makes things much clear. Keeping this in mind, I guess it makes senses to: 1. Modify osinfo_os_get_devices() to recurse into OSs it 'Derives' and 'Clones' as well. 2. Modify the DB to reflect 'Derives' relationship as well as 'Upgrades' for many of the OSs, for example fedoraN both derives from and upgrades fedoraN-1. ? -- Regards, Zeeshan Ali (Khattak) FSF member#5124
