[rhn-users] shutdown services when upgrading

[Jim Pelton]

This is a relatively simple question, I think...

So I'm trying to develop a good strategy for updating (with up2date) 
some web servers and several other production level boxes.  My question 
arose out of the need to update httpd on the web farm.  If I go ahead 
and update, will the rpm %pre and %post scripts (or whatever does this 
type of thing) shutdown the httpd service, update and then bring it back 
up?

Also, is there an easy way to go about finding this information, with 
out just doing a test run on a test machine?  It is important to 
understand the way these things work if any sort of automation is to be 
trusted!

Thanks much,

Jim
