The internet access in developing countries may be getting better, but that is primarily city focused, and even in cities, the cost of internet access is still high. In a large developing country like India (where I live), a huge percentage of the population lives away from the cities. Unlike people living in the cities, the people in the small towns are more likely to be open to using Fedora, for reasons of both cost and principles. I work with the Fedora FreeMedia program, and I send out around 50 Fedora DVDs a month, out of which a good number is to individuals and organizations in rural areas. Regarding the use of deltarpms, if it were not for the availability of deltarpms, a large number of Fedora systems in developing countries will remain not updated, or very irregularly updated, which will result in a large number of Fedora users being exposed to security vulnerabilities. The users will not be able to help it, because the cost for internet access here is often tied to bandwidth usage, and even a weekly update of Fedora using the full rpms will be too expensive. Add to that the unreliability of the internet access, leading to download errors for bigger packages, and most users will choose not to update. So from what I know, based on my personal experience, and my experience in the Fedora FreeMedia program, the Fedora install and Live DVDs are still very relevant, and deltarpms are extremely relevant for developing countries. Please do not sound the death knell for these highly essential tools, based just on the experience in developed countries. p.s. Thanks to poma for bringing this mail thread to my attention. I was not on the Fedora devel list so far. I have now subscribed to the Fedora devel list, so as not to miss such important discussions. :-) -- Regards, Rejy M Cyriac (rmc) -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
