[Pkg-net-snmp-devel] Bug#887423: snmptrapd: Systemd service unit definition of snmptrapd ignoring settings in /etc/default/snmptrapd

[Ingo Rauschenberg]

Package: snmptrapd
Version: 5.7.3+dfsg-1.7
Severity: normal

Dear Maintainer,

I have to use the snmptrapd with some special mib-files from the
vendors of my hardware suppliers (like Dell, Brocate, Enterasys, Sun,
Rittal, ...).
Therefor I defined the MIBSDIR environment variable on my own in the
file /etc/default/snmptrapd.

With the introduction of systemd there is a systemd service unit file
provided in the package snmptrapd, located at
/lib/systemd/system/snmptrapd.service
Unfortunately this file contains the environment MIBSDIR hard coded.

Because I would prefer to change only files in /etc for configuration
issues I would ask, if you can change the systemd service unit file like
this:
---
[Unit]
Description=Simple Network Management Protocol (SNMP) Trap Daemon.
After=network.target
ConditionPathExists=/etc/snmp/snmptrapd.conf

[Service]
EnvironmentFile=/etc/default/snmptrapd
Type=simple
ExecStart=/usr/sbin/snmptrapd -f $TRAPDOPTS
ExecReload=/bin/kill -HUP $MAINPID

[Install]
WantedBy=multi-user.target
---

With the parameter EnvironmentFile you can read the configuration from
/etc/default/snmptrapd and so you only have one file for the old and the
new init way.

I hope this helps and you can realize again the flexibility of the
configuration.

Best regards,
Ingo Rauschenberg
