    "rotate 0" would give you a single logfile, true, but it wouldn't combine that
    with the previous one in any way. The meaning seems to be "throw away the
    current logfile and start a new one". What I'm looking for is "throw away
    all the entries in the logfile that are more than one week old and keep the
    rest", say. I don't think "rotate 0" enables you to do that.

    Looking at it another way, logrotate seems to be indifferent to the actual
    contents of a logfile.
