Users don't have to start kded by hand, it's dbus-activated when apps need it. Starting kdeinit is enough. In theory it's all autostarted, but I had to start kdeinit before ctest for instance, so that ctest doesn't wait for kdeinit to exit. I want kded to be less and less important in the future, it shouldn't mix on-demand services and plasma-session startup stuff, and some of the kded modules themselves should be turned into library code (like I did for kbuildsycoca, next are cookies etc.). And some services should move to kiod (like I did for kpassswdserver). Overall I don't want kded to be a required runtime dependency. dbus starting async is an issue no matter what, but unrelated to which process starts all this. kdeinit5 --kded isn't what I was talking about (that's only used in startkde), but rather dbus activation of kded (which you can test with `qdbus org.kde.kded5 /modules/desktopnotifier` or /modules/favicons if you have libkonq installed, or just /org/kde/kded5 to start with). - David ----------------------------------------------------------- This is an automatically generated e-mail.
