Adding auxiliary parameters breaks snmpd.
Just upgrade to 11.1-U1 at the request of Dru (see bug 28431). Noticed that cacti isn't updating stats on the box. I have a bunch of "extend" parameters to run scripts when certain OIDs are queried. If I take those statements out of the "Auxiliary Parameters" then /etc/local/snmpd.conf is generated correctly. If I leave them in I get a broken snmpd.conf. The community string is missing (though that option is filled in in the GUI) and the sysLocation is set to one of my auxiliary parameters...
sysLocation extend hstemp /mnt/tank/home/vol1/unix/cacti/homeseer/hs-temp-stats
