You could use urpmi to install updates, as it won't ask for any manual assistance compared to the update applet.
The messages shown during updates are usually contained in a README file.
After installation you can still find and view those, and in doubt you can ask here.
For apache that would be /usr/share/doc/apache/README.update.urpmi
Important package setup changes
Starting with new version 2.4, multiple upstream and packaging changes in
file setup will requires manual intervention after upgrade to migrate
configuration:
- modules files are now located under /usr/lib64/httpd/modules, instead of
/usr/lib64/apache/modules, but the relative path from apache base directory
%didn't change
- all LoadModule directives are now located in files located under
/etc/httpd/conf/modules.d, and are likely to duplicate directives previously
located in /etc/httpd/conf/httpd.conf
- /etc/httpd/conf/httpd.conf now contains only core directives, many other are now
located in various files under /etc/httpd/conf/conf.d
- additional upstream changes documented here:
http://httpd.apache.org/docs/2.4/upgrading.html
Although that only applies for an update to apache 2.4, which is in place for quite some time already.
For rpmdrake I don't know what messages you mean.
What assistance in particular do you require currently. Do apache and rpmdrake work as expected after the updates? Then everything is good.
