Subject: php4: postinst corrupts apache config file

Package: php4
Version: 4.1.2-7.0.1
Severity: grave

Setting up php4 (4.1.2-7.0.1) ...
I see you have apache webserver installed and so far you haven't
used the apache module version of php4 in your apache. If you
want to use it, you should reconfigure the apache webserver and
select to load the php module. I can call the apacheconfig script
now for you to do it, or you can insert the following line into
/etc/apache/httpd.conf manually:

LoadModule php4_module /usr/lib/apache/1.3/libphp4.so

Do you want me to run the apacheconfig script now [y/N] ? y

What we have here is that

1. php4 postinst script doesn't uncomment the php4's LoadModule line while
letting us believe it actually does it.
2. what is much more important, the postinst script rewrites unrelated parts
of /etc/apache/httpd.conf and breaks the web server config file. That's why
I tagged the bug as grave.

Cheers,
