Bug#959191: release-notes: mention configuration file split in logrotate

[Christian Göttsche <cgzones@googlemail.com>]

Package: release-notes

With version 3.14.0 [1] logrotate split the configuration for btmp and
wtmp into separate configuration files.
There are bug reports regarding this issue: #945932, #928516, #922045.

Over at #946779 Julien suggested adding a section (5.3.10 ?).

Maybe the section can be like the following:

   The shipped configurations for "/var/log/btmp" and "/var/log/wtmp" have
   been split from the main configuration file (/etc/logrotate.conf) into
   separate standalone files (/etc/logrotate.d/btmp respectively
   /etc/logrotate.d/wtmp).

   If you had modified /etc/logrotate.conf in this regard, make sure
   to re-adjust the two new files to your needs and drop any references to
   (b|w)tmp from the main file, to avoid logrotate skip rotation due to a
   duplicate definition.


Best regards,
   Christian Göttsche
