+Upgrading from <2.2.6-r4
 

 
 
 
+The Apache ebuilds have used /etc/apache2/apache2-builtin-mods for
+a very lone time to select the built-in modules during compile time. This
+behaviour has several disadvantages though:
+
+
+
+  
+    Selecting built-in modules during the initial merge is not possible.
+  
+  
+    Portage does not know which modules have been installed. This is especially
+    annoying for binary packages.
+  
+  
+    Portage will try to overwrite apache2-builtin-mods on every
+    upgrade.
+  
+
+
+
+To rectify this situation /etc/apache2/apache2-builtin-mods has
+been deprecated and migrated to the new APACHE2_MODULES
+USE_EXPAND variable. To convert your custom module selection to the new
+format use the following command:
+
+
++$ echo APACHE2_MODULES=\"$(sed '/^mod_/s/mod_\(.*\)\s\+\(shared\|static\)/\1/;t n;d;:n' /etc/apache2/apache2-builtin-mods)\" >> /etc/make.conf
+$ rm /etc/apache2/apache2-builtin-mods
+
+(You can now safely upgrade apache:)
+$ emerge -uvp '>=www-servers/apache-2.2.6-r4'
+
+
+
+Additionally to the new APACHE2_MODULES the local USE flags have
+been cleaned up:
+
+
+
+  
+    All MPM USE flags have been moved to the APACHE2_MPMS
+    USE_EXPAND variable
+  
+  
+    no-suexec is now suexec
+  
+  
+    static-modules is now static
+  
+
+
+
+For a detailed description of old and corresponding new USE flags see
+below.
