No solid answer, I seldom see such an effect.

One possibility, many services have a default config file
installed with the service.  They also may have a "local"
config file that takes precedence if present.  "local"
may be done by location or by a specifice name variation.

If you are configuring your services by modifying the default
config file, it may be overwritten by an update.
