Interesting. I have elogind installed, too, and I also have that
mountpoint at /sys/fs/cgroup/elogind, but nevertheless, uninstalling
cgroupfs-mount sufficed for me. IIRC I didn't do a reboot since
Package: udev
Version: 240-5

I do not have cgroupsfs-mount installed, but i have elogind.
It apparently mounts /sys/fs/cgroup/unified, so this is enough for
udev to think it is under systemd.
A typical /proc/self/cgroup is :
1:name=elogind:/
0::/
So it is my understand
Hi Felipe,
thanks for looking into this.
I've made a very quick test of the patch you provided this morning,

It works for me.

Hi,
I manage to reproduce this with systemd, in a Virtualbox VM.
here are the steps, after booting with systemd as init
* stop udev
# systemctl stop systemd-udevd
make sure there is no 'systemd-udevd' process list in pstree
* start udev in background like this
# setsid --fork /lib/systemd
Hi,
With the help of snapshot.d.o, I've found that the problem first appeared in
239-8.
I've also been able to trigger it by restarting udev and running 'udevadm

Still no insight on what is the factor causing this to happen on some machines
and not on others.

Could you try downgrading udev to either 239-15 or 240-1 and report back
with the results.
