+CentOS 6 and 7, Fedora 43
+~~~~~~~~~~~~~~~~~~~~~~~~~
 
 CentOS is another popular baseline among Linux distributions, being a free
 derivative of the RedHat Linux, upon which many other distros are based as
 well. These systems typically use the RPM package manager, using directly
 `rpm` command, or `yum` or `dnf` front-ends depending on their generation.
 
+In fact, most of the instructions directly apply to much newer distributions
+like Fedora 43.
+
 For CI farm container setup, prepared root filesystem archives from
 http://download.proxmox.com/images/system/ worked sufficiently well.
+For Fedora, https://images.linuxcontainers.org/images/fedora/43/amd64/default
+nightly image was used.
