Hello,

Should it also handle "hotplug" events? It might be useful to peek at
the prior art in the area even if only to avoid making the same mistakes
they did. In the grander scheme of things, we should also investigate if
third-party software like FDO's HAL can make use of the new API.
I'm also pondering if this new daemon can/should replace ifwatchd.

Cheers,
