Package: loganalyzer
Version: 3.6.6+dfsg-1
Severity: serious
Tags: patch
Justification: Policy 6.2

Hello there,

loganalyzer's postinst creates
/etc/apache2/conf-available/loganalyzer.conf during installation, but
fails to detect that it has already created this file during subsequent
postinst runs, which leads to failure to configure during package
upgrades. This appears to stem from copy-and-waste during converting the
package to work with both apache2.2 and apache2.4. :)

Please see the following transcript for details:

:) fernst@fernst:~$ ls -al /etc/apache2/*/*logana*

The following patch allows the package to be configured again:
