Description Jan Stodola 2023-08-16 16:20:59 UTC 
The installer gets confused when mount point assignment is used in webui, mount point mappings are configured and then one mapping is removed and configured again. A video will demonstrate it.

Reproducible: Always

Steps to Reproduce:
1. Run a webui installation on a system with pre-existing partitioning (in my case it was a default installation of Fedora 38 Workstation in UEFI mode)
2. Select "Mount point assignment", create mappings for /boot, /, /boot/efi, /home
3. Remove the mapping for /boot/efi
4. Create a new mapping for /boot/efi
Actual Results:  
webui reports "Duplicate mount point." and the device previously selected for /home is de-selected. Next attempts to set the correct device for /boot/efi and /home mount points are not successful, since the selected device is set for both mount points.

Expected Results:  
Able to add a mapping for /boot/efi

I think it's probably worth considering this for a Final blocker (assuming we go ahead with WebUI), it's a close call for me whether it really *is* one.
