BTW, the "hg help clone" still mentions using "cp -al REPO CLONE" to do that:

    In some cases, you can clone repositories and the working directory using 
full hardlinks with

      $ cp -al REPO REPOCLONE

    This is the fastest way to clone, but it is not always safe. The operation 
is not atomic (making sure REPO is not modified during the
    operation is up to you) and you have to make sure your editor breaks 
hardlinks (Emacs and most Linux Kernel tools do so). Also, this is
    not compatible with certain extensions that place their metadata under 
the .hg directory, such as mq.
