Description of problem: # systemctl daemon-reload Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1) Version-Release number of selected component (if applicable): systemd-223-2.git65c85ef.fc24.x86_64 kernel-4.2.0-0.rc4.git2.1.fc24.x86_64 (I'm assuming that this is kdbus related. Will have to try again after upgrading to latest systemd.)
I tried to reproduce this and I can confirm that I also see the error message. However in my case systemd actually reloads its configuration, i.e. I can see Reloading log message and also it complains about some unit files not being world readable. I am running kdbus on kernel-4.2.0-300.fc23.x86_64 and systemd is circa two weeks old git master.
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase
kdbus is no more.
