Associated release criterion
This test case is associated with the Fedora_40_Beta_Release_Criteria#Custom_partitioning release criterion. If you are doing release validation testing, a failure of this test case may be a breach of that release criterion. If so, please file a bug and nominate it as blocking the appropriate milestone, using the blocker bug nomination page.


This test case ensures that the data in the /home directory is retained and usable on a Btrfs layout after another Fedora is installed on the same partition.


  1. Install Fedora 39 or 40 from any Edition or Spin which uses Btrfs filesystem by default. Use Automatic storage configuration during disk partitioning.
  2. On the installed system, create some distinct files and directories in your home directory or directly in /home

How to test

  1. Select a Fedora 40 installer for any Edition or Spin which uses Btrfs filesystem by default.
  2. Boot the installer using any available means.
  3. Proceed to the installer's main screen, making sensible choices, and enter the Installation Destination screen.
  4. In Installation Destination, use Advanced Custom (Blivet-GUI) partitioning
  5. On the disk drive containing the existing Fedora installation, make sure the existing partitions formerly used as /boot and /boot/efi (if applicable) are reformatted and the same mountpoints are again assigned to them. (Alternatively, you can create new partitions and leave the old ones intact and without mountpoints).
  6. In the list of existing btrfs volumes, locate the home subvolume of the existing installation and set the /home mountpoint to it.
  7. You can delete all the other btrfs subvolumes, or you can keep them intact, but without any mountpoints assigned.
    • This refers to the root subvolume, but you can also see some additional subvolumes present as well, like root/var/lib/machines or root/var/lib/portables.
  8. Create a new root subvolume and set the / mountpoint to it.
    • If you already have a root subvolume, because you decided to not delete the old one, that's not a problem, just name the new one differently.
  9. Perform the installation and reboot the machine. At the initial setup, it's recommended to use all the same settings as for the first installation.
  10. After logging in, check that your home directory or /home contains the files you created on your previous system (check their contents as well).

Expected Results

  1. The expected partition layout should be created on the target device(s).
  2. The install process should complete successfully and the installed system should boot as expected.
  3. The partitions and subvolumes which were assigned some mountpoints in the installer should be mounted, and the partitions and subvolumes which weren't assigned any mountpoints shouldn't be mounted.
  4. Your personal files on your /home partition must be intact.
