Why is most of my SSD LVM?

Do show output of lsblk and also look at lsblk --fs

The default[1] partitioning done by installer does create about three partitions:

  • EFI System partition (mounted to /boot/efi)
  • Partition with filesystem (mounted to /boot)
  • The PV that takes the rest of space

Within the PV three LV are created:

  • For /
  • For /home
  • For swap

Personally, I never accept the default and rather use my custom scheme.
