Software and technical details of Fedora Server 35 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 Server 35 using a real not virtual machine!
The kernel is 5.14.10 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 35 Server.
Installed packages are 604 occupying 1.7G space:. Note, this is Fedora Server Install, not minimal install. The server install includes the web console – cockpit version 254.

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 1.6G 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 35 installer to do default installation asking you to reclaim the disk space. We used the whole disk for the installation.
By default Fedora Server 35 uses.

  1. xfs – file system
  2. lvm – root, home and swap partitions
  3. boot, root and home on separate partitions
  4. vfat – efi partition.
