After enabling the plugin, create a file called
/etc/yum/pluginconf.d/versionlock.list which will be the list of
packages to version lock. The file excepts package names in the form
rpm -q <package name> --queryformat "%{NAME}-%{VERSION}-%{RELEASE}\n "
or easier the standard rpm -q <package name> format.

 For upstream/Fedora the versionlock plugin now comes with a command,
so, for example, to versionlock your Xorg drivers you just do:

# yum install yum-plugin-versionlock
[...]
# yum versionlock xorg-x11-drv-\*
[...]
#

Ok, a few clarifications is needed then...

The yum versionlock <packagename>-\* command adds a 0: to the
/etc/yum/pluginconf.d/versionlock.list file

Is the 0: needed and what does it mean? man pages yum-versionlock and
yum-versionlock.conf does not make mention of this entry in the file.

The 0: is the epoch of the package. It is normally left off when people read it but for the computer it is best to have everything completely specified so there is no ambiguity.

Also should all entries be added in this way or can you still hand
edit the versionlock file.

you can hand edit it.


Glad to help, I am on a bit of a documentation warpath today. Internal
lack of documentation at my current contract is driving me a bit
mental. A few years back I was cleaning up some old computer lab that
had IBM mainframes from the 60ties and discovered some old
documentation. I was absolutely amazed at the level of detail and
precision of these documents and wished a bit that more documentation
could be like that... granted we live in a very different world today
and things work differently and change much faster... but still...
<sigh>


thanks for the help. we need it for the docs especially.
