    <para>
      The <filename>lastlog</filename> file is a database which contains info
      on the last login of each user. You should not rotate it. It is a sparse
      file, so its size on the disk is much smaller than the one shown by
      "<command>ls -l</command>" (which can indicate a really big file if
      you have a high UID). You can display its real size with
      "<command>ls -s</command>".

    <para>
      Large gaps in uid numbers will cause the lastlog program to run
      longer with no output to the screen (i.e. if mmdf=800 and last
      uid=170, program will appear to hang as it processes uid 171-799).
