The yum-autoupdate script was developed by Scientific Linux.

The primary goal is a simple, clean, and automatic way of keeping certian
elements of the system up to date.

You can configure a number of useful variables in /etc/sysconfig/yum-autoupdate.
A sample copy of the default values is included here.

It has a number of hooks for modifying the way it interacts.  One of the
most useful hooks was contributed by the community - PRERUN/POSTRUN.  You
can use these hooks to run most anything you want before or after the update
operation.  A sample script is provided in the documentation directory which
demonstrates one of the many useful things you could do with these hooks.

An augeas lense is also provided.  It will trigger on the 'augeas' package
and load the lense for you at that time.  When removed, it will clean up the
lense so you don't have extra stuff left behind.
