Should be, if you are using kickstart to build the servers.

You can also config yum to not update particular packages - with risk of 
security patches leaving your machine less secure. There are som 
versionlock and so forth yum plugins.

Ideally, you would create an rpm package for your application.
In the spec Require a specific kernel version.
Run yum update with --skip-broken, so that kernel updates that would 
stop the app working.

When you know the require package (kernel is updated), bump and rebuild 
the rpm, makine it available (createrepo) in a local repo, and have your 
local repo configured on all the machines.

How's that ?
