DESCRIPTION:I overview how OS management is done at Meta. We run millions o
 f Linux servers and we have to make sure that OS gets updated on all of th
 em in a given period of time. To do that we developed several products: Me
 talOS (Image based version of CentOS)\, Antlir (image builder) and Rolling
  OS Update (a service that keeps a set of DNF repos in sync with upstream 
 repos and uses them to update OS )
