SMF support for clamsmtp

[mamalos]

Hi there!

There's no SMF support for clamsmtp package, so I've written one (by sort-of copy-pasting the relevant pieces from clamd's SMF) and the relevant rc script from FreeBSD.

My SMF file looks like this:

<?xml version='1.0'?>
<!DOCTYPE service_bundle SYSTEM '/usr/share/lib/xml/dtd/service_bundle.dtd.1'>
<service_bundle type='manifest' name='export'>
  <service name='pkgsrc/clamsmtp' type='service' version='0'>
    <create_default_instance enabled='false'/>
    <single_instance/>
    <dependency name='fs' grouping='require_all' restart_on='none' type='service'>
      <service_fmri value='svc:/system/filesystem/local'/>
    </dependency>
    <dependency name='network-service' grouping='require_all' restart_on='none' type='service'>
      <service_fmri value='svc:/network/service'/>
    </dependency>
    <dependency name='clamd' grouping='require_all' restart_on='none' type='service'>
      <service_fmri value='/pkgsrc/clamav:clamd'/>
    </dependency>
    <dependency name='config' grouping='require_all' restart_on='none' type='path'>
      <service_fmri value='file:///opt/local/etc/clamsmtpd.conf'/>
    </dependency>
    <method_context working_directory='/var/clamav'>
      <method_credential group='clamav' user='clamav'/>
    </method_context>
    <exec_method name='start' type='method' exec='/opt/local/lib/svc/method/clamsmtp start' timeout_seconds='0'/>
    <exec_method name='stop' type='method' exec='/opt/local/lib/svc/method/clamsmtp stop' timeout_seconds='0'/>
    <exec_method name='refresh' type='method' exec='/opt/local/lib/svc/method/clamsmtp refresh' timeout_seconds='0'/>
    <property_group name="startd" type="framework">
      <propval name="duration" type="astring" value="contract"/>
      <propval name="ignore_error" type="astring" value="core,signal"/>
    </property_group>
    <stability value='Evolving'/>
    <template>
      <common_name>
        <loctext xml:lang='C'>ClamAV SMTP filter for postfix daemon</loctext>
      </common_name>
    </template>
  </service>
</service_bundle>

And the relevant rc script (/opt/local/lib/svc/method/clamsmtp) looks like this:

#!/sbin/sh
#
# $NetBSD: clamd.sh,v 1.1 2014/03/11 14:34:39 jperkin Exp $
#
# Init script for clamd(8)
#

. /lib/svc/share/smf_include.sh

PIDFILE="/var/clamav/clamsmtp.pid"
CONFIGFILE="/opt/local/etc/clamsmtpd.conf"

case "$1" in
start)
        /opt/local/sbin/clamsmtpd -f ${CONFIGFILE} -p ${PIDFILE}
        ;;
stop)
        kill `/usr/bin/head -1 ${PIDFILE}`
        ;;
refresh)
        # Re-open any log files and reload the database
        kill -HUP `/usr/bin/head -1 ${PIDFILE}`
        ;;
*)
        echo "Usage: $0 {start|stop|refresh}" >&2
        exit 1
        ;;
esac

These are just my 2c. I suppose both files can be refactored to be more complete, but I'm new in Solaris-based OS', so... :)

Thanks, I implemented something like this and committed to upstream pkgsrc. Note that SMF itself has a built-in process manager, so things like PID files are typically not needed and for simply daemons not even start up scripts are required (i.e. binaries can be called directly).
