Bug 45606 – Apache 2.0.49 ebuild creates incorrect symlink

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Steve 2004-03-24 08:24:08 UTC]

After updating Apache from version 2.0.48-r1 to 2.0.49, I was unable to restart the server and received the following error message:

root # /etc/init.d/apache2 restart
* Apache2 has detected a syntax error in your configuration files:
Syntax error on line 24 of /etc/apache2/conf/apache2.conf:
Cannot load /etc/apache2/modules/mod_auth.so into server: /etc/apache2/modules/mod_auth.so: cannot open shared object file: No such file or directory

I did some looking and found that the new installation changed the location of Modules from /usr/lib/apache to /usr/lib/apache/modules, but the symlink form /etc/apache2 did not update.  After updating the symlink, the server started fine. 

Below is my listing of the pertinent directories both before and after the upgrade:

Reproducible: Always
Steps to Reproduce:
1. Emerge Apache-2.0.49
2.
3.

Actual Results:  
The directory structure of /usr/lib/apache changed, moving all loadable modules 
into a modules subdirectory.  The corresponding symlink in /etc/apache (modules) 
did not update to point to the new modules directory in /usr/lib/apache.

Expected Results:  
The ebuild should have deleted the old symlink and created a new one in 
/etc/apache2 that pointed to /usr/lib/apache/modules rather than 
/usr/lib/apache.

[Comment 1 Martin Holzer (RETIRED) 2004-03-24 08:40:00 UTC]

did you etc-update your files ?

[Comment 2 Steve 2004-03-24 08:55:10 UTC]

Yes, I ran etc-update on the files, merging new changes to my existing files for apache2.conf and vhosts.conf, and replacing all others (/etc/conf.d/apache2, /etc/init.d/apache2, /etc/apache2/conf/commonapache2.conf).  I did this on both servers that I updated.
