I'm setting up my patch process. I have a static group of machines for my initial patch testing. I'd like to set up a 20% Pilot group, but don't want to be dealing with keeping it up to date, nor do i want my IT team to have to refer to a list to see if a user is part of the pilot group or not.
I want to select 20% by creating a query that returns all users with a first name that starts with a letter between A and J. This will give me 20% of our environment that is pretty much random. It's also easy for the IT team to remember that if a person's first name is between A and J then they are piloting patches.
How can i do this?
