>Description:
mv(1) man page says the following:
> As the rename(2) call does not work across file systems, mv uses cp(1)
> and rm(1) to accomplish the move. The effect is equivalent to:
>
> rm -f destination_path && \
> cp -pRP source_file destination && \
> rm -rf source_file
But, cp(1) is actually used only if source_file is not the regular file.
Then, mv(1) of the regular file cannot inherit its file flags.
>How-To-Repeat:
$ > /foo
$ chflags nodump /foo
$ ls -lo /foo
-rw-r--r-- 1 shirai user nodump 0 Jun 24 14:06 /foo
$ mv /foo /var/tmp
$ ls -lo /var/tmp/foo
-rw-r--r-- 1 shirai user - 0 Jun 24 14:07 /var/tmp/foo
>Fix:
The following is a bug fix patch for FreeBSD-current.
