Odd diff -qr / /mnt "Only in " results

Mark Millard-4
Context: head -r365932 (on a Rock64). But this could well not
be new.

First a look at the / context and then the /mnt/ :

# ls -laT /

But when I do the "diff -qr / /mnt" I get the following "Only in "
notices:

Only in /mnt: .cshrc
Only in /mnt: .libs
Only in /mnt: .profile
Only in /mnt: .rnd
Only in /mnt: .snap
Only in /mnt: COPYRIGHT

Only in /mnt: proc
Only in /mnt: rescue
Only in /mnt: sbin
Only in /mnt: sys
Only in /mnt: tmp
Only in /mnt: usr
Only in /mnt: var
Only in /mnt: wrkdirs

It still does the diff's inside the likes of /usr/ and /mnt/usr/ .

This is not something that I normally do so I've no clue what range
of versions do this.

Well, after the complete diff I went looking in places that I
had expected a few differences to show (but did not). I found
some files with differences.

So it appears that at least some of those "Only in " notices
did result in lack of comparisons in the areas reported.

Bad interpretation on my part:
The "Only in" /mnt notices are from diffing /mnt and /mnt/mnt .
I did not notice at the time.

I've still not figured out how I ended up finding more different

operator errors, I guess.
