I have now rewritten my original prose including all the suggestions
and have also spend time to verify everything so it is repeatable.
Q4. second bullet
Another way to pin package "foo" to a certain version is to use the
versionlock plugin.
If you are using the latest Fedora (12) then the plugin can be
installed using yum install yum-plugin-versionlock
Alternatively if you are using Redhat 5.4/Centos 5.4 or another OS
that does not yet have the latest yum available, then the plugin must
be obtained manually from the current git repository for yum which is
http://yum.baseurl.org/gitweb.
The files you need will be found in the yum-utils/plugins/versionlock
part of the git tree.
Copy versionlock.py to /usr/lib/yum-plugins/versionlock.py
Copy versionlock.conf to /etc/yum/pluginconf.d/versionlock.conf
Create /etc/yum/pluginconf.d/versionlock.list
All files should be root.root with 644 permissions.
The plugin will only work for yum versions 2.3.3 and later
To add files that you want version locked, use the following yum command:
yum versionlock <package-name>
you can also use wildcards
yum versionlock <package-name>-*
The config file uses the following format:
rpm -q <package name> --queryformat "%{EPOCH}:%{NAME}-%{VERSION}-%{RELEASE}\n "
or easier the standard rpm -q <package name> format with the EPOCH
number of the package prepended.
If no EPOCH is specified in the package then the number will be 0.
