So far, no one created a bridge under JBoss' legs while
it's up & running. Bridge creation happens on hosts and
not in the engine-core machine. So up until now we had
JBoss up & running in his machine, and when it installed
a new host, a script would run on that new host to change
networking for the new bridge to be created. During this time
JBoss is monitoring the process from a (safe) distance.
Now, an web-app running on top of JBoss (you may know
it as engine-core) is doing network changes while the
app-server (JBoss...) is running and listens to 0.0.0.0
and maybe locally as well to specific ports. In this
situation network changes should happen only if you /know/
it's safe, or even better- do it /before/ starting JBoss.
So when JBoss starts network should be stable.

Why doesn't DOS ever say "EXCELLENT command or filename!"
