Comment # 16 on bug 968405 from Dr. Werner Fink

(In reply to Dominique Leuenberger from comment #14)

/etc/sysconfig/services is the only true documentation:

 # Type:        yesno
 ## Default:     no
 #
 # Do you want to disable the automatic restart of services when
 # a new version gets installed?
 #
 DISABLE_RESTART_ON_UPDATE="no"

 ## Type:        yesno
 ## Default:     no
 #
 # Do you want to disable the automatic shutdown of services when
 # the corresponding package gets erased?
 #
 DISABLE_STOP_ON_REMOVAL="no"

Don't know which wiki says something different here.
