Some monitoring tools will run into errors when sysDescr field is empty. This was the case for cacti 1.2.8 that i'm using to monitor my network. Ideally the sysDescr field would contain some information from the overview of luci, e.g. the Model, Firmware and Kernel-Version fields, but i am stranger to OpenWRT, so I'm unable to do that.

Makes use of all available runtime options that can be passed to
mini_snmpd such as -I listen_on interface
Run-tested on trunk on ar71xx. Please review the init script regarding procd
monitoring interfaces, though everything else due to the conversion to
procd should be and done properly, if not overkill compared to most
other script bundled with openwrt.
The main benefit of all this is now larger routers can run multiple
instances of mini_snmpd on different ports, to get around the MIB hard
coded 4 interface/mountpoint limits.
Due to somewhat lacking dev / package maintainer docs except for
http://wiki.prplfoundation.org/wiki/Procd_reference writing this script
took longer than it should. You can see it's evolution here:
https://github.com/hojuruku/openwrt-packages/blob/mini_snmpd/net/mini_snmpd/files/mini_snmpd.init
If everything in it is found to be sane, please include it to the
openwrt wiki on procd as an example.
Due to procd / uci /sbin/validate_data cbi element datatype (uciname) being used
to check uci config, the configuration file now only takes openwrt uci network names not
physical network names as it did before.

Like busybox the package Makefile has depends for all runtime
dependencies needed by the init script. mini_snmpd only depends on libc
squashed commits:
mini_snmpd: fix typo to fix procd triggers calling daemon binary directly instead of init script - misuse of $PROG var
mini_snmpd: enable SSP & mini_snmpd to start by default and listen on lan
mini_snmpd: disable RELRO blocker in Makefile after consulation
mini_snmpd: add smarts to init script to detect if ubusd hasn't started yet
mini_snmpd: fix init script - ubus -S doesn't print meaningful errors to give the user
mini_snmpd: Makefile roll back Makefile PKG_RELEASE to 1 for feng shui
