Going back to a minimal system : strange problem
by Nicolas Kovacs 02 Mar '18

02 Mar '18

Hi, Some time ago I wrote a little script elaguer.sh ("élaguer" means "to prune") which simply removes all packages that are *not* part of a minimal installation. First I created a list of packages that make up a minimal CentOS installation. On a fresh install, I would do something like this: # rpm -qa --queryformat '%{NAME}\n' | sort > minimal.txt Here's the resulting list of packages. I added a comment on top: https://github.com/kikinovak/centos-7-server-lan/blob/master/config/pkglist… And here's the script to prune the installation, e. g. remove everything that's not on the list. https://github.com/kikinovak/centos-7-server-lan/blob/master/elaguer.sh This script worked perfectly for some time. But now it seems like something has changed somewhere under the hood. Because when I run it now, the script fails at the final package removal stage. One curious detail: it seems like it tries now to remove 'yum' and 'systemd', so 'yum' exits with an error. But it didn't do that before, so my guess is either 'yum' behaves differently now, or package dependencies are calculated differently. Anyway, I'm a bit clueless here. Any suggestions?

I have two systems both running CentOS 7.4 one shows pid_max as 32768 the other shows pid_max as 49152 Why might that be ? I would have thought they would be the same. I have not changed them. Thanks, Jerry

Any alternatives for the horrible reposync
by Dennis Jacobfeuerborn 28 Feb '18

28 Feb '18

Hi, I'm currently trying to mirror a couple of yum repositories and the only tool that seems to be available for this is reposync. Unfortunately reposync for some inexplicable reason seems to use the yum config of the local system as a basis for its work which makes no sense and creates all kinds of problems where cache directories and metadata gets mixed up. Are there any alternatives? Some repos support rsync but not all of them so I'm looking for something that works for all repos. Regards, Dennis

Everyone, Have any of you installed ubiguiti wireless routers on your network? It looks like the setup requires the use of software; they have some packages that are ready made for Ubuntu and Debian, but not RedHat https://www.ubnt.com/download/unifi/unifi-ap-ac-pro Have any of you tried or succeeded in installation this on Centos 7.4?

Cloud image_index: is 1801-01 a release?
by Nicholas Timkovich 26 Feb '18

26 Feb '18

I load CentOS cloud images into our infrastructure for our users to use, and I have a script that looks at https://cloud.centos.org/centos/7/images/image-index, picking what has the highest revision, to find the new hotness. Up until the most recent image, they've all appeared in there; is this changing going forward? How can I automatically find the newest one and its revision tag? The untagged "latest" ones (linked to by the https://wiki.centos.org/Download page) don't appear in the sha256sums file, so I couldn't even compare sums. Can I petition for keeping the cloud image-index up-to-date? -- Nick Timkovich | Software Engineer | Computation Institute, University of Chicago | npt(a)uchicago.edu
