This thread originated by a request to "clean up" the output on newer ubuntu machines which use "snap" packages as /dev/loopN . Let's not turn that into a drastic change
It could certainly be multiple sets of patches. But let's face it, df's utility for ordinary interactive use has degraded significantly with time due to all the random filesystems people have been adding, and we shouldn't keep our heads in the sands about this. df's default needs to change, one way or another.
I mean c'mon, here's the output of 'df' on the Ubuntu 18.04.3 LTS workstation I'm typing this particular message on. In any sane system there would be only four lines of non-header output (for tmpfs etc, /, /home, and /media/eggert/B827-D456), but df is outputting 28 lines. This is ridiculous.
