Bug#737825: hangs on systemd-tty-ask-password-agent reproduced

[Antoine Beaupré]

Package: systemd
Version: 215-17+deb8u3

I have reproduced the issues described in the bug reports #774153 and
#737825 (they look like duplicates to me, really).

After a minor apt upgrade run here (libgraphite2 stable update and
darktable backport upgrade), needrestart asked me if I wanted to restart
some services which seemed to need restart.

I checked all boxes - i seem to recall that udev was checked off by
default but i rechecked it. It seems this may have been the cause of the
problem, because after that, I ended up having problems with the
following services which wouldn't restart properly:

 * colord.service
 * ModemManager.service
 * udev.service
 * udisks.service
 * udisks2.service

I would also have my logs more or less (1/sec) flooded with:

fév 15 19:55:46 marcos systemd[1]: Looping too fast. Throttling execution a 
little.

Installing a new package (sopel) also would hang on the
systemd-tty-ask-password-agent call, oddly enough. Restarting udev
unhang the install:

Paramétrage de sopel (6.3.0-1) ...
Warning! D-Bus connection terminated.
Failed to wait for response: Succès
invoke-rc.d: initscript sopel, action "start" failed.
dpkg: erreur de traitement du paquet sopel (--install) :
 le sous-processus script post-installation installé a retourné une erreur de 
sortie d'état 1

It also allowed me to restart the other services.

I also tried `systemctl daemon-reexec` as recommended in #774153, not
sure what impact it had.

There was definitely something wrong, but it's recoverable. This could
be a udev bug of some sort, but since this is all systemd now... who
knows!? ;)

Thanks,

A.

Bug#749268: systemd --user and sd-pam processes keep running after logout

[Antoine Beaupré]

Package: systemd
Version: 208-8
Followup-For: Bug #749268

This still affects jessie and is a significant annoyance because of all
the clutter in the process table, especially for shell servers.

Here this also affects users like polipo and tahoe...

A workaround I was told about was to use KillUserProcesses=
in logind.conf(5) - but then that will break screen and similar tools.
