Default [Snort-users] database output plugin sensor_name parameter and ACID strangeness

I've been doing some experimenting using multiple senors and a single
console box, and have noticed the following behavior
=20
Even if I set sensor_name in the output plugin list, it is not set in
the list of sensors... rather, it will say "0.0.0.0:ce1" (the interface
does not have an IP address and it is a gigabit nic interface named ce1)
=20
If I go into the "sensor" table in the snort database, I can change the
hostname field to whatever I like. That works until I restart the
sensor... Unfortunately, it's only persistent until I restart the Snort
sensor. Then, a new interface is added to the list named "0.0.0.0:ce1"
and all the events end up attached to that sensor id.
=20
Some advice would be appreciated!

My output line looks like:
output database: alert, mysql, dbname=3Dsnort, sensor_name=3Dtest_ce0
user=3Dsnort password=3Dfoo host=3D10.99.99.99
