Hi Evgeni
Still sorry for this late answer, I'm back home now and will be able to answer more quickly. >Any pointers how to reproduce your setup would be awesome. Yes, and good news, I was able to precise the problem and to reproduce it on another jessie + backports box : To reproduce the problem, both boxes need : (1) sysinit (no systemd) as system startup (2) cgroupfs-mount installed Both boxes use kernel 4.5.0-0.bpo.2-amd64 # dpkg --list | grep cgroup ii cgmanager 0.33-2+deb8u2 amd64 Central cgroup manager daemon ii cgroup-bin 0.41-6 all control and monitor control groups (transitional package) ii cgroup-tools 0.41-6 amd64 control and monitor control groups (tools) ii cgroupfs-mount 1.1 all Light-weight package to set up cgroupfs mounts ii libcgmanager0:amd64 0.33-2+deb8u2 amd64 Central cgroup manager daemon (client library) ii libcgroup1:amd64 0.41-6 amd64 control and monitor control groups (library) ii libpam-cgfs 2.0.0-3~bpo8+1 amd64 PAM module for managing cgroups for LXC # dpkg --list | grep sysvi ii sysvinit-core 2.88dsf-59 amd64 System-V-like init utilities ii sysvinit-utils 2.88dsf-59.3 amd64 System-V-like utilities # stat /proc/1/exe Fichier : « /proc/1/exe » -> « /sbin/init » Taille : 0 Blocs : 0 Blocs d'E/S : 1024 lien symbolique Périphérique : 4h/4d Inœud : 14273 Liens : 1 Accès : (0777/lrwxrwxrwx) UID : ( 0/ root) GID : ( 0/ root) Accès : 2016-06-05 16:32:37.623997097 +0200 Modif. : 2016-06-05 16:32:37.619997096 +0200 Changt : 2016-06-05 16:32:37.619997096 +0200 Créé : - cgroupfs-mount change /sys/fs/cgroup mount point without this package : # mount |grep "/sys/" pstore on /sys/fs/pstore type pstore (rw,relatime) fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime) cgroup on /sys/fs/cgroup type tmpfs (rw,relatime,size=12k) with this package # mount |grep "/sys/" pstore on /sys/fs/pstore type pstore (rw,relatime) fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime) cgroup on /sys/fs/cgroup type tmpfs (rw,relatime,size=12k) cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,relatime,cpuset,release_agent=/run/cgmanager/agents/cgm-release-agent.cpuset,clone_children) cgroup on /sys/fs/cgroup/cpu type cgroup (rw,relatime,cpu,release_agent=/run/cgmanager/agents/cgm-release-agent.cpu) cgroup on /sys/fs/cgroup/cpuacct type cgroup (rw,relatime,cpuacct,release_agent=/run/cgmanager/agents/cgm-release-agent.cpuacct) cgroup on /sys/fs/cgroup/blkio type cgroup (rw,relatime,blkio,release_agent=/run/cgmanager/agents/cgm-release-agent.blkio) cgroup on /sys/fs/cgroup/devices type cgroup (rw,relatime,devices,release_agent=/run/cgmanager/agents/cgm-release-agent.devices) cgroup on /sys/fs/cgroup/freezer type cgroup (rw,relatime,freezer,release_agent=/run/cgmanager/agents/cgm-release-agent.freezer) cgroup on /sys/fs/cgroup/net_cls type cgroup (rw,relatime,net_cls,release_agent=/run/cgmanager/agents/cgm-release-agent.net_cls) cgroup on /sys/fs/cgroup/perf_event type cgroup (rw,relatime,perf_event,release_agent=/run/cgmanager/agents/cgm-release-agent.perf_event) cgroup on /sys/fs/cgroup/net_prio type cgroup (rw,relatime,net_prio,release_agent=/run/cgmanager/agents/cgm-release-agent.net_prio) cgroup on /sys/fs/cgroup/pids type cgroup (rw,relatime,pids,release_agent=/run/cgmanager/agents/cgm-release-agent.pids) I don't remember why this package was originally installed; I guess I was trying to install unprivileged lxc on the box. I will retrace a step by step installation without this package to check if it's required for this purpose Please, what would be the following steps ? Thanks, Best regards XQ
