Title:
  "killall -u snmp" in a pre-install step kills any running snmpd

Status in net-snmp package in Ubuntu:
  Triaged
Status in net-snmp package in Debian:
  New

Bug description:
  If I am running snmpd (which I was) and I install snmp (which I did),
  it kills snmpd due to a pre-install step of the snmp package that
  calls a 'killall -u snmp' :(

  Found the pre-install step here:

  user at host3:~$ cat  /var/lib/dpkg/info/snmp.preinst 
  #! /bin/sh

  set -e

  action="$1"

  killall -u snmp  2>/dev/null || true

  if [ "$action" = upgrade ]
  then
    if [ -L /usr/share/doc/snmp ]; then
      rm -f /usr/share/doc/snmp
    fi
    if [ -d /usr/doc/snmp ]; then
      rm -rf /usr/doc/snmp
    fi
  fi


  exit 0
