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

In my observation at least once every 45 days there is either Kernel security update or glibc one. And each one of them required machine reboot. And all Linux distributions are based both on Linux kernel and on glibc. Thanks in advance for your insight!

Halo Valeri, let's think about what a hpc cluster is for. Second, one should always ask the question where security is to be applied,then one can come to the following decision: - The firewall is placed in front of the cluster. - After you have found a safe base for this, you freeze it. - We have a rsync of centos and epel on the head node.>From here, we can always reinstall a node (tftp / http)- To relieve the internal network printing, I create rpm packages that are installed on the nodes. All this happened about 3 years ago. Centos 1511 was established as a stable variant for the environment. It was one of my many different tasks in my work. The physicists and mathematicians who count there need high durations. My decision much on Centos because: - free - Maintaining until the year 2024, longer than the cluster will live. My way in the beginning was hard, because I had to learn everything from the scratch and I'm no longer the youngest, but my feeling gave me right. Sincerely Andy
