Raspbian Jessie. How can I configure SNMP to work with a pass command (shell script) on a read-only disk? I read that smnp.conf can have a tempFilePattern specified, but what should I use? Tried /var/log and it doesn't seem to work (no such instance exists at this OID). Works perfectly with a RW file system. Does the Raspberry Pi version of Jessie even use that variable?
