Thanks to all offers free service to provide Centos. Why? After I had the BIOS for the laptop T440 & docking station had I had immediately after the first installation works, without any failures. Since I know how hard such a work is, I thank everyone in the community to make that possible. Without a stable base I can not perform my Linux tests. Since I often have the time micht Rolling releases like ArchLinux or every half year, I know at the latest after a year, a Fedora update to perform is CentOS exactly the correct. I do not need the GUI support as in OpenSuSE, because who comes times from the shell knows what I mean. Most cluster nodes in my work are computing machines with an average run time of 220 days, usually over a year before they need a reboot. When I think about my virtual Windows 10, which every week requires a restart. I had already more than 30 distros active in my hands, but none read so easily. Of course you can always improve something here and there and yet it comes on a good basis. Furthermore, I find the handling of rpm easily understandable. Small supplement to my repo: - I provide the packages of my work - They are not signed because I do not see you directly as an additional repository for everyone, rather than as an exponential fundus. - Each external repostory changes the basic system. - new dependencies to the packages. - Users also indirectly depend on it. - Repositories in the past have already led to a new split of the basis. Best example: Debian -> Ubuntu -> Linux Mint. I don't like that point at all. - The holder is bound, in a certain way, to the care and demand of the Community. - I definitely miss the time. All in all ... thanks to everyone Andy
