kf5.kio.core: KSambaShare: Could not find smb.conf!

This was on my desktop while booting with openrc, when i switched to boot with systemd as PID1 k3b worked as normal.

I rebooted to openrc and checked my xorg log. Found dbus wasn't started correctly, and solved it , see Init #Dbus .

The Error message stayed the same.

NOTES  :
when booting with openrc (99.9% of the time) i don't have a valid logind session
I have Udisks2 installed because some things require it, but until now i never needed its functionality.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Re: [openrc] k3b not finding drives

I looked a bit deeper into what happened with systemd as PID1 wrt udisks2 .
before starting k3b udisks2 was not active at all, after starting it was .

man udisks showed udev and a daemon work together to provide udisks functionality.
The udisks2 pacakge has one systemd service-file in usr/lib/systemd/system/udisks2.service .
I checked that and found it starts the udisksd daemon.

I had not enabled that service however, so what was starting it automagickally ?

Then i remembered the most annoying property of booting systemd :
starting stuff on demand without user interaction or approval .

I booted back into openrc, ran /usr/bin/udisksd in a terminal and k3b in another terminal .
Everything worked as expected.

I'll consider creating an openrc service file for udisks2 .
I vastly prefer having as little daemons running as possible, so whether i'll start udisksd at boot or use a script to start/stop it just for k3b remains to be decided.
