"include" command in a zone-file with dynamic updates...

Some remarks if you are using dynamic updates based on 8.2.4REL .

1. The dynamic updates are only kept in memory and the DB file is dumped at intervals to prevent data loss. These intervals based on number of updates and time are hard coded in the source. Of course the DB files are dumped when terminating the program via ndc or signal 15.

2. As a result of 1. all "include ..." statements and manual ordering vanish with the first dump.

If you are using dynamic updates you must not mess with the DB files anymore.
You have to use "nsupdate" instead which is quite slow but keeps the serial number and data base OK.
