Trying to get my toybox tests to pass with TEST_HOST=1 I encountered
regressions in mv between the coreutils 9.1 in Devuan Daedalus (fork of
Debian Bookworm) and the coreutils 9.7 in Devuan Excalibur (Debian
Trixie). Both changes violate posix 2024 from
https://pubs.opengroup.org/onlinepubs/9799919799/utilities/mv.html
1) touch file1 file2; mv -i file1 file2 < /dev/null; ls file1
On Bookworm file1 is still there, in Trixie it's gone. "Lack of no" is
taken as yes. This violates this part of posix-2024:
the mv utility shall write a prompt to standard error and read a line
from standard input. If the response is not affirmative, mv shall do
nothing more with the current source_file and go on to any remaining
source_files.
2) touch file1 file2; echo n | mv -i file1 file2 && echo yes
The return code of mv -i when given "n" was 0 in Bookworm and 1 in
Trixie. This violates this part of posix-2024:
EXIT STATUS
The following exit values shall be returned:
0
All requested files (excluding files where a non-affirmative
response was given to a request for confirmation) were successfully moved.
>0
An error occurred.
Again, both tests passed on Devuan Daedalus (I.E. Bookworm/9.1) but not
Excalibur (Trixie/9.7).

P.S. I have no idea if they're fixed in current git, I tried to bisect
as a courtesy before repoting but can't build git because there's no
./configure and ./bootstrap wants more prerequisite packages than I'm
willing to install. But they're still in the fully updated distro.
