+\subsection{New Message Identification Format}
+We are starting to add unique message indentifiers to each message (other
+than debug and the Job report) that Bacula prints. At the current time
+only two files in the Storage Daemon have these message identifiers and
+over time with subsequent releases we will modify all messages.
+
+\smallskip
+The message identifier will be kept unique for each message and once
+assigned to a message it will not change even if the text of the message
+changes. This means that the message identifier will be the same no matter
+what language the text is displayed in, and more importantly, it will allow
+us to make listing of the messages with in some cases, additional
+explanation or instructions on how to correct the problem. All this will
+take several years since it is a lot of work and requires some new programs
+that are not yet written to manage these message identifiers.
+
+\smallskip
+The format of the message identifier is:
+
+\begin{verbatim}
+ [AAnnnn]
+\end{verbatim}
+where A is an upper case character and nnnn is a four digit number, where
+the first charcter indicates the software component (daemon); the second
+letter indicates the severity, and the number is unique for a given
+componet and severity.
+
+\smallskip
+For example:
+
+\begin{verbatim}
+ [SF0001]
+\end{verbatim}
+
+The first charcter representing the componend at the current time one of
+the following:
+
+\begin{verbatim}
+ S Storage daemon
+ D Director
+ F File daemon
+\end{verbatim}
+
+\smallskip
+The second character representing the severity or level can be:
+
+\begin{verbatim}
+ A Abort
+ F Fatal
+ E Erropr
+ W Warning
+ S Security
+ I Info
+ D Debug
+ O OK (i.e. operation completed normallly)
+\end{verbatim}
+
+So in the example above [SF0001] indicates it is a message id, because of
+the brackets and because it is at the beginning of the message, and that
+it was generated by the Storage daemon as a fatal error.
+\smallskip
+As mentioned above it will take some time to implement these message ids
+everywhere, and over time we may add more component letters and more
+severity levels as needed.
