The following error message seems wrong:
bash$ umask 027
bash$ cat /dev/null >/tmp/foo
bash$ ls -l /tmp/foo
-rw-r----- 1 witr bin 0 Jun 20 12:13 /tmp/foo
bash$ mv /tmp/foo ~/foo
mv: /home/witr/foo: set owner/group: Operation not permitted
bash$ ls -l foo
-rw-r----- 1 witr witr 0 Jun 20 12:16 foo
mv(1) says that a move across filesystems is like a cp -pr, and
cp(1) says:
-p Causes cp to preserve in the copy as many of the modification time,
access time, file flags, file mode, user ID, and group ID as al-
lowed by permissions.
If the user ID and group ID cannot be preserved, no error message
is displayed and the exit value is not altered.
So, why the error message?
