Thats a great question.

I provide my own repos which sync to Centos/Plus/RPMForge/Gitco upon  
my choosing, normally once a month.

I then test any new updates before going live with a foreach loop,  
yumming hosts in my list.

I did the same is an MS$ env and am unsure of a better way.  But I've  
never managed more then 1,000 nodes.

Any one care to share there methodology?

- Brian

This is precisely what I do, and it works very well.  I have 'multithreaded' my 
script so that several systems update in parallel, so that it doesn't take 
-forever-.  I've also broken it out into a couple processes for clustered 
environments (I have a lot of web clusters) so that only one web server in a 
cluster ever updates at once.

In essence, my methodology for handling updates to domUs matches my general 
attitude about them: treat them like normal machines, and use the oldschool 
voodoo handed down from our fore-admins to manage them.  This wheel has already 
been built.  :-)
