Package: sasl2-bin
Version: 2.1.26.dfsg1-13+deb8u1
Followup-For: Bug #791814
Adding "/" didn't resolve the problem.
Oddly enough, executing the script from /etc/init.d/ and from a local directory
changes everything, and I think the problem has something to do with systemd.
Here's why :
========================================
root@messagerie[10.10.10.20] ~ # /etc/init.d/saslauthd start
[ ok ] Starting saslauthd (via systemctl): saslauthd.service.
root@messagerie[10.10.10.20] ~ # pgrep -a saslauthd
root@messagerie[10.10.10.20] ~ #
========================================
Here, we see that systemd is invoked. Let's try to copy that file to a local
folder and run it from there :
========================================
root@messagerie[10.10.10.20] ~ # cp /etc/init.d/saslauthd TEST/
cp: overwrite ‘TEST/saslauthd’? y
root@messagerie[10.10.10.20] ~ # cd TEST/
root@messagerie[10.10.10.20] ~/TEST # chmod +x saslauthd
root@messagerie[10.10.10.20] ~/TEST # ./saslauthd start
[ ok ] Starting SASL Authentication Daemon: saslauthd.
root@messagerie[10.10.10.20] ~/TEST # pgrep -a saslauthd
5231 /usr/sbin/saslauthd -a rimap -c -m /var/run/saslauthd -O localhost -n 5
5232 /usr/sbin/saslauthd -a rimap -c -m /var/run/saslauthd -O localhost -n 5
5233 /usr/sbin/saslauthd -a rimap -c -m /var/run/saslauthd -O localhost -n 5
5234 /usr/sbin/saslauthd -a rimap -c -m /var/run/saslauthd -O localhost -n 5
5236 /usr/sbin/saslauthd -a rimap -c -m /var/run/saslauthd -O localhost -n 5
root@messagerie[10.10.10.20] ~/TEST #
========================================
Here, we see that systemd was not invoked.
Another interesting information is that I tried to debug the
/etc/init.d/saslauthd script by puting echo statements at different places. The
echo isn't being printed in this case :
==================================================
#! /bin/sh

# Exit if the package is not installed
[ -x "$DAEMON" ] || exit 0
# Load the VERBOSE setting and other rcS variables
.. /lib/init/vars.sh
echo "this is printed"
# Define LSB log_* functions.
# Depend on lsb-base (>= 3.0-6) to ensure that this file is present.
.. /lib/lsb/init-functions
echo "this is not printed"
==================================================
So probably /lib/lsb/init-functions has something to do with it ?
Here's the trace :
==================================================
root@messagerie[10.10.10.20] ~/TEST # pkill saslauthd
root@messagerie[10.10.10.20] ~/TEST # pgrep -a saslauthd
root@messagerie[10.10.10.20] ~/TEST # /etc/init.d/saslauthd start
this is printed

.. ok

==================================================
Yassine.
