both on how large the file is allowed to become, and how many versions
of the file will be saved each time the file is opened.</para>
-<para>The <command>size</command> option for files is simply a hard
-ceiling on log growth. If the file ever exceeds the size, then <command>named</command> will
-not write anything more to it until the file is reopened; exceeding
-the size does not automatically trigger a reopen. The default behavior
-is not to limit the size of the file.</para>
-<para>If you use the <command>versions</command> log file option,
-then <command>named</command> will retain that many backup versions
-of the file by renaming them when opening. For example, if you choose
-to keep 3 old versions of the file <filename>lamers.log</filename> then
-just before it is opened <filename>lamers.log.1</filename> is renamed
-to <filename>lamers.log.2</filename>, <filename>lamers.log.0</filename> is
-renamed to <filename>lamers.log.1</filename>, and <filename>lamers.log</filename> is
-renamed to <filename>lamers.log.0</filename>. No rolled versions
-are kept by default; any existing log file is simply appended. The <command>unlimited</command> keyword
-is synonymous with <command>99</command> in current <acronym>BIND</acronym> releases.</para>

+stop writing to the file unless it has a <command>versions</command> option
+associated with it. If backup versions are kept, the files are rolled as

+until some out-of-band mechanism removes or truncates the log to less than the
+maximum size. The default behavior is not to limit the size of the
