    Tar is indeed a most excellent program for copying directory trees, since
    even in this modern century cp fails to correctly handle hard links. Sigh.

    Still, if you are using tar, be sure to use it correctly:

    ( cd srcdir && tar cf - . ) | ( cd destdir && tar xpf - )

    You don't want it going off in the current directory and mangling things
    just because of a little typo in a directory name.

    Stephen.

    PS If I'm right, the new tar fixes something gtar got wrong: setting
    permissions on "." when it is part of the archive, which of course it is
    when you copy directories in this way. This may surprise new users, even
    though it is the only sensible result.

    PPS Who's for adding a "cp -h" option to copy preserving hard links?
