Public bug reported:
(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.
