Date: 2008jun25 OS: Linux Q. What is that packagekitd program that's running on my system? I didn't start it! A. In RedHat/Fedora/CentOS its part of the PackageKit package. The description of that is: PackageKit is a D-Bus abstraction layer that allows the session user to manage packages in a secure way using a cross-distro, cross-architecture API. The deamon, packagekitd, is started on demand when you run dnf and it stops after a while of non-use. More info: http://www.packagekit.org
