Description of problem:

My customer is a hosting partner, they test each errata before applying to
hundreds of machines.  They have asked if we roll out errata on a schedule,
rather whenever the updates are ready.

They acknowledge for critical and security updates those would not be on a
schedule.  But for all the other errata they would like to be able to plan and
budget for their time.  Knowing when those non-critical errata come out would be
helpful.
