Package: systemd Version: 239-11~bpo9+1 Severity: normal Tags: patch Dear Maintainer,
When I upgrade my systemd, I found there is a "nobody" group created automatically. I was wondering what caused that. After tracing down the behavior, I figured out the following line in /usr/lib/sysusers.d/basic.conf triggered it. "u nobody 65534 - /nonexistent /usr/sbin/nologin" Then I started to trace code from https://salsa.debian.org/systemd-team/systemd.git I think there is a bug in debian/extra/make-sysusers-basic Skipping the GID when generating basic.conf may cause the above behavior.
