Package: udev Version: 240-5 Followup-For: Bug #918764 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 understanding from the source code that manager->cgroup should contain '/'. A debugging session breaking on on_post() very unhelpfully indicates that 'manager', 'manager->cgroup', 'userdata' and other helpful variables have been optimized out... (I only use elogind to satisfy the overly broad dependencies of libpolkit-qt5-1-1, but that is another bug, #794537). -- Package-specific info: -- System Information: Debian Release: buster/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'oldoldstable'), (500, 'unstable'), (500, 'oldstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-2-amd64 (SMP w/2 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to fr_FR.UTF-8), LANGUAGE=fr_FR.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to fr_FR.UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) LSM: AppArmor: enabled Versions of packages udev depends on: ii adduser 3.118 ii libacl1 2.2.52-3+b1 ii libblkid1 2.33.1-0.1 ii libc6 2.28-5 ii libkmod2 25-2 ii libselinux1 2.8-1+b1 ii libudev1 240-5 ii lsb-base 10.2018112800 ii util-linux 2.33.1-0.1 udev recommends no packages. udev suggests no packages.
