Description:

systemd should not include the hardware access group "kvm" in "/usr/lib/sysusers.d/basic.conf".
"qemu" or "qemu-headless" comes with it own configuration for the "kvm" group. When qemu is installed it leads to the warning message:

Jul 27 15:00:51 systemd-sysusers[179]: Two or more conflicting lines for kvm configured, ignoring.

Removing this line from basic.conf solves this.

Additional info:

I'm not sure which configuration should be removed best, the systemd or the qemu one. I would guess the one that systemd comes with, because when qemu* is not installed, there is (imho) no need for a kvm group.

* package version(s)

systemd 234.11-1
qemu 2.9.0-2
qemu-headless 2.9.0-2

* config and/or log files etc.

Steps to reproduce:

install systemd and one of qemu or qemu-headless and boot
