There is no difference between the two (in this case)
except for the "-f" cp option.

copy_files is a function defined in build/script/functions

copy_files()
{
        for FILE in $1
        do
                cp -dpfR $FILE $2
        done
}

The first one is right, the second one will not do what you want.

The second one would copy files under $CDDIR/usr/usr/files.
(double /usr which is wrong)


copy_files $WORKDIR/tmp/usr/* $CDDIR/usr 

would work correctly (except for hidden files/directories)
Confused yet?  :-)
