Package: dbus Version: 1.8.20-0+deb8u1
When trying to boot a Debian Jessie container using systemd-nspawn -
dbus.service fails as the directive OOMScoreAdjust=-900 can't be
applied due to missing privileges in container environments.
dbus.service will report on startup:
Starting D-Bus System Message Bus...
Started D-Bus System Message Bus.
Failed at step OOM_ADJUST spawning /usr/bin/dbus-daemon: Permission denied
dbus.service: main process exited, code=exited, status=206/OOM_ADJUST
Unit dbus.service entered failed state.
This renders the container completely useless, as without dbus neither
machinectl is able to do any kind of introspection, nor does the login
to the container work (service systemd-logind will fail as a result of
this problem).
Upgrading the container image to testing "solves" this issue.
I can reproduce the problem using the following steps (the host where this is executed is running Gentoo, Kernel 4.5.0, systemd-230 git@d656822):
mkdir -p /var/tmp/machines debootstrap jessie /var/tmp/machines/debian-jessie http://httpredir.debian.org/debian cd /var/tmp/machines/debian-jessie
tar cf - . | machinectl import-tar - debian-jessie systemd-nspawn -D /var/lib/machines/debian-jessie passwd -d root systemd-nspawn -D /var/lib/machines/debian-jessie apt-get update systemd-nspawn -D /var/lib/machines/debian-jessie apt-get install -y wget ca-certificates dbus
systemd-nspawn -D /var/lib/machines/debian-jessie /bin/rm /etc/securetty machinectl read-only debian-jessie machinectl clone debian-jessie debian-jessie-test machinectl start debian-jessie-test
machinectl login debian-jessie-test
systemctl -M debian-jessie-test status dbus
