Extremely long names in df output

I am not sure if it's from Xcode or macOS 27, but here is what I get after running df:

/dev/disk3s3                                                                                      228Gi   1.5Gi    15Gi     9%     112  161M    0%   /Volumes/Recovery
devices -- file:///Users/USER/Library/Containers/com.apple.CoreDevice.CoreDeviceService/Data/   1.0Ti     0Bi   1.0Ti     0%       0  9.2E    0%   /Users/USER/Library/Developer/CoreDevice/DeviceFS

It's really annoying. Is there any way to remove this?

That is the DeviceFS FSKit extension, which is what allows you to browse the contents of attached iOS devices directly from the Finder. You can see it System Setting > General > Login Items & Extensions > By Category > File System Extensions. That UI normally allows you to disable the extension, but in this case that doesn’t work, probably because it’s considered ‘built in’. If you’d like to see that change, I encourage you to file a bug about it (please post your bug number, just for the record).

In the meantime, you can avoid this by telling df to only show you APFS volumes:

% df -T apfs
