Package: coreutils
Version: 8.25-2
Severity: normal
Dear Maintainer,
as an extension, coreutils supported moving one file to another, when both
refer to the same file.
This support has been lost after upgrading from 8.23-4 (stable) to
8.25-2. That is, in 8.25-2:
# touch a; ln -f a b; mv a b
mv: 'a' and 'b' are the same file
and both names still exist. While in 8.24-4, the "obvious" happens, i.e.
only "b" is left after the mv command.
It would be wonderful if this extension could somehow survive, as the
new behaviour is rather counter-intuitive (one expects that "mv a b", if
possible, makes b refer to a, and a is gone afterwards).
Thanks!

Shocking, low-quality behaviour from a gnu program to help apple.
In any case. thanks a lot for providing this information - I looked a bit
through the changes, but couldn't find anything specific. It also means the
nice behaviour is not coming back, I need to find another mv, and this bug
ain't a bug.
