we use zcm 11.2 on sles 11.1 servers. Clients: Win7Sp1

as far as I understand it, there are two ways to deploy patches:

a) Over the Mandatory Baseline (of some dyn. group)
b) Deploy Remediation (per patch-bundle)

The problem with b) is that every time you have to create/name a patch-bundle that lands in some folder. After some time this gets a little confusing.

Now the question is:
What happens if we want to clean up these patch-bundles and just delete them? Are the patches then still on the clients?
