That's the default.

The file_clone option uses FICLONE, which only exists on Linux and only
works on certain file systems.  Ccache 4 does use copy_file_range()
though, which is an improvement on all file systems on all platforms
that support it, and which in FreeBSD defaults to block cloning if at
all possible.
