Description tk2345_ 2025-11-03 16:34:31 UTC 
For Fedora WS using "Reinstall Fedora", when using the storage editor to assign mount points for a non-empty btrfs root subvolume and the EFI partition, the storage checker reports "Storage requirements not met. You must create a new file system on the root device.”

Consider improving error handling/message:

1. The message does not state the unmet requirement, "The root device/subvolume is not empty."

2. For "Reinstall Fedora" storage requirements seem to be met, as it requires a non-empty root
device/subvolume. Deleting and recreating the root subvolume removes the "Reinstall Fedora" method.

3. For a btrfs root subvolume one must not create a new file system. Creating a new file system destroys the home subvolume.

Reproducible: Always

Steps to Reproduce:
1. Open storage editor
2. Assign mount points to non-empty btrfs root subvolume and EFI partition
3. Exit storage editor
