I have made a edit to the snmpd.postinst script to add a set -x and I see the following:
Setting up snmpd (5.2.3-4) ...
+ '[' xconfigure = xconfigure ']'
+ adduser --quiet --system --no-create-home --home /var/lib/snmp snmp
+ chown -R snmp /var/lib/snmp

++ '[' '!' '' ']'
++ PERL_DL_NONLAZY=1

++ which invoke-rc.d
+ '[' -x /usr/sbin/invoke-rc.d ']'
+ invoke-rc.d snmpd start

+ exit 0

Which looks like the script is completing... but however it is hanging around:
jamesr at monitor:~$ ps -ef | grep 'pts/0'
jamesr   18071 18069  0 10:28 ?        00:00:00 sshd: jamesr at pts/0
jamesr   18072 18071  0 10:28 pts/0    00:00:00 -bash
root     20741 18072  2 10:34 pts/0    00:00:01 aptitude upgrade snmpd
root     20746 20741  0 10:34 pts/0    00:00:00 /usr/bin/dpkg --status-fd 8 --configure quagga snmpd snmptrapfmt
root     20789 20746  0 10:34 pts/0    00:00:00 /usr/bin/perl -w /usr/share/debconf/frontend /var/lib/dpkg/info/snmpd.postinst configure 5.2.3-1
root     20800 20789  0 10:34 pts/0    00:00:00 [snmpd.postinst] <defunct>

Because its a defunct process I cannot strace it and lsof shows nothing:
jamesr at monitor:~$ sudo strace -fF -p 20800
attach: ptrace(PTRACE_ATTACH, ...): Operation not permitted
jamesr at monitor:~$ sudo lsof -p 20800

Any further information I can provide let me know I will be happy to help.
