Package: systemd
Version: 204-5
Severity: important
I've been investigating a dist-upgrade failure, where rsyslog fails to
upgrade properly from its wheezy to jessie version.
The problem is, that the wheezy version shipped the
/etc/systemd/system/syslog.service symlink (pointing to rsyslog.service)
in the package and in jessie we use i-s-h to create the symlink upon
installation. During the upgrade, there is a time frame where the
syslog.service symlink has been removed by dpkg, but postinst has not
been run yet to (re)create the symlink. If at this point a daemon-reload
is issued (e.g. from another package via invoke-rc.d), systemd loses
track of the rsyslog process, which is still running.
So in rsyslog.posinst, when invoke-rc.d rsyslog restart is called,
systemd thinks rsyslog.service is dead and instead of restarting, starts
the service. As the old rsyslog process is still running, this fails.
To reproduce the issue, one can follow those steps:
- Make sure rsyslog is installed and running.
status: step1.txt
- rm -f /etc/systemd/system/syslog.service
- systemctl daemon-reload
status: step2.txt
- re-create symlink: systemctl enable rsyslog.service
- systemctl daemon-reload
status: step3.txt
(at this point systemd thinks, rsyslog.service is active (dead), while
the rsyslog process is still happily running
- "systemctl restart rsyslog.service" produces
Job for rsyslog.service failed. See 'systemctl status rsyslog.service'
and 'journalctl -xn' for details.
Atm, the only workaround I see is to *manually* kill the old rsyslogd
process in postinst via kill $(cat /run/rsyslogd.pid) before the daemon
is restarted via invoke-rc.d rsyslog restart.
This is of course an ugly hack and I assume syslog-ng will be effected
by this in a similar way.
not a great solution.
