Hello List, I'm ironing out details to upgrade a few systems to CentOS7. My servers have BMC with Serial over LAN support. In C5 and C6, I determined how to have BIOS/POST, kernel, and serial console access. I'm reading up on the method to accomplish the pieces with C7. Presently SoL output works, so I see BIOS/POST messages and the GRUB boot list. My changes to enable serial

Hi, On my minimal installation of CentOS 7, here's what I have in /etc/default/grub: GRUB_TIMEOUT=0 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rd.lvm.lv=centos_amandine/root \ rd.lvm.lv=centos_amandine/swap \ video=1024x768 \ quiet" GRUB_DISABLE_RECOVERY="true" According to the official documentation, pressing any alpha...

I have built a CentOS 8 base image from a kickstart, for use in OpenStack. This image boots fine but the problem I have is that I can't stop udev from renaming the network device from eth0 to ens<something>. I have /etc/sysconfig/network-scripts/ifcfg-eth0 with the correct HWADDR defined in it, and have set net.ifnames=0 and biosdevname=0 in the grub configuration, but nothing I have
