pserv doesn't listen to interfaces that come up after pserv get started

[Adam Collard]

We had to use a workaround of writing a maas-pserv.override containing http://paste.ubuntu.com/6844470/

This is because the bridge interface came up after maas-pserv was started and didn't listen on the new interface.

This might be a dupe of an existing bug.

Maybe use an upstart configuration that restarts pserv whenever a restart event occurs - reload would be better

[Gavin Panella (allenap)]

pserv should thus handle HUP or some other signal.

Can pserv detect new interfaces itself I wonder...

It could, by periodically checking. However, this is something that Upstart does natively, and notices as soon as it happens. An Upstart job to detect a change in NICs and reload the pserv job (which sends a HUP) would be simple and very effective I think.

That's true, but I was trying to avoid more dependency on packaging for the
correct operation of MAAS itself.

Fair point.

I think we can build a better product overall by absorbing more of the packaging assets into upstream MAAS. It would blur the division between upstream and Ubuntu, but things like detecting changes to NICs is fairly platform-specific, and MAAS upstream is meant for Ubuntu anyway.

Put another way, we, as upstream maintainers, should take more responsibility for the end-user's experience by reducing the delta between upstream MAAS and installed MAAS.

Totally +1
