Gday everyone,

Since the last systemd update (229) I haven't been able to run my
systemd user instance.

I'm getting this error when I try to run "systemctl --user status":
Failed to connect to bus: No such file or directory

Running strace reveals that it tries to connect to kdbus which isn't
available on the current kernel:

open("/sys/fs/kdbus/1000-user/bus", O_RDWR|O_NOCTTY|O_CLOEXEC) = -1
ENOENT (No such file or directory)

I've tried disabling kdbus adding "kdbus=0" as kernel parameter but that
didn't work.

I had the exact same problem with Ubuntu (Testing) und Fedora these
days. I had some timers with "OnBootSec=0Min".

And when I started such a timer they crashed the dbus user session.  I
found it out after moving .config/systemd/user to something else,
rebooting and then moving and starting services and timers one by one.
I hope that helps.

Niels
