| I really need some help on this named logging.. please.  I have named logging to a file named.log, which is setup in logrotate
| to rotate weekly for 52 weeks...  The problem I have is that named writes to named.log but when logrotate rotates the log,
| moves named.log to named.log.1 and creates the new named.log ... named writes to the named.log.1 and not the "new" empty file
| named.log .. Maybe named doesnt know about the log rename.. I dunno... ACK please help... below is some info.

Just add an 'ndc reload' after the rotate. named does not see that the file has been renamed
as it has it still open. ndc reload will make named close and reopen the logfiles, such that
it will then open the new file. You don't even have to create an empty file, named will do that too.
