This seems more like a freeze exception.

For a different reason than cited in the bug:

the installer must be able to:
    Create mount points backed by ext4 partitions, LVM volumes or btrfs volumes, or software RAID arrays at RAID levels 0, 1 and 5 containing ext4 partitions

Oddly, I don't really see an installation criteria for disk encryption. The closest I can find is this post-install basic criteria which pretty explicitly doesn't mention upgrades.

This does feel like a pretty easy path to unintended data loss though.

Based on Beta's Criteria, which I believe is valid because of final criteria stating "All Fedora 43 Beta Release Criteria must be met."

I believe this violates "Assign mount points to existing storage volumes" at https://fedoraproject.org/wiki/Fedora_43_Beta_Release_Criteria#Custom_partitioning

I clarified the bug report here:
https://bugzilla.redhat.com/show_bug.cgi?id=2396646#c6

Given that using the whole disk device for a filesystem, instead of using partitions, is possibly quite a niche use case, there is no data loss, and this layout is definitely not offered by default, I'm not completely sure whether this qualifies as a blocker. Even though the criterion says:

The installer must be able to create and install to any workable partition layout using any file system and/or container format combination offered in a default installer configuration.
https://fedoraproject.org/wiki/Fedora_43_Final_Release_Criteria#Disk_layouts

So yes, it should be covered... but still feels quite an obscure use case for me.

Based on my assumption that there is one partition spread across the entire disk with an encrypted filesystem mounted as /home. It should definitely be reusable, as the above seems a perfect use case to have.

Discussed at the 2025-09-22 (blocker / freeze exception) review meeting:

This is accepted as a violation of "the installer must be able to: ... Assign mount points to existing storage volumes", noting the "Re-using /home" footnote below, in the specific case that the /home to be reused is both encrypted and a direct-on-disk filesystem (not a partition). This is a fairly uncommon case but we decided it was potentially common enough (given the webui's ability to create such a layout) that we should block on it.
