GEFS, the "Good Enough File System" on the horizon for OpenBSD

Filesystems on OpenBSD have come in two varieties, UFS1 or UFS2 . Ori Bernstein has set out to possibly introduce a new option, the "Good Enough File System", which Ori describes as

"a new, crash-safe, snapshotting, copy on write FS that I wrote for 9front, and which I am in the process of moving to OpenBSD.

Ori gave a presentation about the work at EuroBSDCon 2026, and posted a summary message titled GEFS on OpenBSD: A very early preview to tech@, inviting hacking and testing:

Before anyone asks: I am *not* proposing to put
this in tree for a while yet.

What is it
----------
So, as people may have seen at EuroBSD, I've got a
rough, buggy, issue-filled preview of GEFS running
on OpenBSD. The port is NOT ready for production,
and data loss is currently expected, especially on
error.
