That's a matter of proper processes. I'm managing my entire system configuration
using a central (subversion) repository hosting the FAI config space. Any kind
of configuration change is only done in this repository. Afterwards, I run
softupdates to enable those changes (or add new packages) on the target host. In
fact, I have measures in place that ensure that other admins will get notified
if anyone ever changes something on a host other than via a softupdate.

This may seem like overkill for changing a single line in a config file or
something. But it allows, for example, migrating an entire setup from A to
totally new (and different) servers and client hosts at location B without the
slightest fear that some change might have been forgotten over the years. By the
way, A == TU München, B == TU Darmstadt.

Of course, these tools also do their job in some or the other way. I just never
found that much of a difference, they just seemed much more complicated. But
that's a matter of taste I guess.
