Bug Description

Binary package hint: irqbalance

[using 0.55+20091017-3ubuntu2 on lucid]

irqbalance gets enabled unconditionally upon installation. The user's answer to the question whether it should be enabled (upon installation or dpkg-reconfigure) gets ignored:

| $ cat /etc/default/irqbalance
| #Configuration for the irqbalance daemon
| #Should irqbalance be enabled?
| #Balance the IRQs only once?
| $ sudo dpkg-reconfigure -ftext irqbalance
| stop: Unknown instance:
| Configuring irqbalance
| ----------------------
| Enable the irqbalance daemon to balance IRQs on SMP systems and systems with
| hyperthreading.
| Would you like to enable irqbalance? n
| irqbalance can run in one shot mode, where the IRQs are balanced only once. This
| is advantageous on hyperthreading systems such as the Pentium 4, which appear to
| be SMP systems, but are really one physical CPU.
| Would you like to balance the IRQs once? y
| irqbalance start/running, process 1496
| $ cat /etc/default/irqbalance
| #Configuration for the irqbalance daemon
| #Should irqbalance be enabled?
| #Balance the IRQs only once?

=> dpkg-reconfigure managed to change the ONESHOT setting but not the ENABLED setting.

The problem is caused by a confusion over where to use "ENABLED" and where "ENABLE". I'm attaching a trivial patch which fixes the problem.
