Hi, Some time ago I wrote a little script elaguer.sh ("?laguer" 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 '%{...

I just did a fresh minimal install of centos 7 on new hardware. While playing around with window systems I removed X windows like so: >yum remove "X Window system" and then tried to re install >yum group install "X Window system" which gives this error: Maybe run: yum groups mark install (see man yum) No packages in any requested group available to install or

Here's my little script: https://github.com/kikinovak/centos/blob/master/7.x/scripts/00-elaguer-paquets.sh Any existing CentOS installation (GNOME, KDE, Web Server, etc.) can be stripped down to a minimal install by simply running it. I've tried this with different scenarios, and it works perfectly. Thank you everybody for your input. Niki -- Microlinux - Solutions informatiques du...

...reconfigured by the hosting company, so I thought it wouldn't be a bad idea to start stripping that stuff first. Here's a little script I wrote, which essentially strips down any CentOS-7 installation to a minimal core system: https://github.com/kikinovak/centos/blob/master/7.x/scripts/00-elaguer-paquets.sh The script parses the 'minimal' package list and then just removes everything that's not on the list. Now I tried running that on an existing CentOS-7 "Web Server" installation. I ran it, rebooted... and I got dropped to a console that suggested to run journalct...
