Technical details of a default CentOS 8.0.1950 minimal installation

Storage

Default installation on a single disk, which has only free space on you disk or you reclaimed all the occupied space during installation. CentOS 8 needs at least 18G space for this kind of installation (Minimal Install with Standard Addon), so if you select a destination disk, which has less than 18G of space you should delete existing partitions to free up space or let CentOS 8 installer to do default installation asking you to reclaim the disk space. We used the whole disk for the installation.
By default CentOS 8 uses.

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