Software and technical details of Fedora Server 36 including cockpit screenshots

This article is for those of you who do not want to install a whole new operating system only to discover some technical details about the default installation like disk layout, packages included, software versions, and so on. Here we are going to review in several sections what is like to have a default installation of Fedora 36 Server using a real not virtual machine!
The kernel is 5.17.9 it detects successfully the Threadripper 1950X AMD and the system is stable (we booted in UEFI mode).
The installation procedure uses default options for all installation setups – Minimal network installation of Fedora 36 Server

Storage

Default installation on a single disk, which has only free space on your disk or you reclaimed all the occupied space during installation. Install Fedora Server 35 needs at least 1.8G of free space for the default installation, so if you select a destination disk, which has less than 20G of space you should delete existing partitions to free up space or let Fedora Server 36 installer to do default installation asking you to reclaim the disk space. We used the whole disk for the installation.
By default Fedora Server 36 uses.

  1. xfs – file system
  2. lvm – root partition
  3. efi, boot, root are on separate partitions
  4. vfat – efi partition.
  5. zram – loop device, which is a RAM drive that uses compression
