Title:
Daemons are restarted in the current session cgroups
Status in “systemd-shim” package in Ubuntu:
New
Status in “systemd-shim” package in Debian:
New
Bug description:
(forwarded from the relevant bug report raised in Debian BTS and
adapted for upstart as PID1)
Daemons which are not spawned via an upstart job (eg. those with
initscripts, ifupdown hooks and similar) are not detached from the
current logind session cgroups. This causes the session to linger in
the closing state until the background processes are either terminated
or manually moved by root into the root cgroups, so seat ACLs are not
released.
A (very crude) workaround on Debian Jessie is using cgm movepidabs /
$$ to "break out" of the current session before performing any
administrative action which could result in a daemon (re)start, but
cgmanager is not installed by default on Trusty and the version of cgm
shipped with it lacks the movepidabs subcommand (even though the
MovePidAbs method in the DBus interface does exist).
Note that this affects anything that uses service, invoke-rc.d,
ifupdown hooks (like ifup on PPPoE links) or initscripts directly.
Upstart jobs are not affected because they inherit their cgroup set
from PID1 (which lives in the root cgroup).
Nota bene: I'm raising the issue on systemd-shim on advice from its
maintainer, even though it's unclear at what level this behavior
should be addressed.
