Note that there are some significant non-Unix filesystems along the way. In particular, a few years later: "Reimplementing the Cedar File System Using Logging and Group Commit", Robert Hagmann, Xerox PARC. SIGOPS Operating Systems Review, November 1987.

That's the origin of the journaling approach used in post-FFS unix file systems through the 90s. (I don't count ext2 as "post-FFS", as it's basically FFS on a disk with LBA addressing)

As the old saying says: "You can tune a filesystem, but you can't tune a fish."

is there some metaphor i’m missing or is it just funny?

The phrase originates with the ‘BUGS’ section of the 4.2BSD man page for the `tunefs(8)` command, for the Berkeley Fast File System that is the topic of the OP article.
