Btw, this has the consequence that if /etc/default/snmpd is removed, then the default variables in /etc/init.d/snmpd will be of no use since the daemon won't start.

So either /etc/default/snmpd is mandatory (with an interface definition inside), or there's a 127.0.0.1 missing in SNMPDOPTS defined in /etc/init.d/snmpd

My 2 cents,
