Yes. There is the general dm_event mechanism (which I wouldn't recommend)
or with newer kernels you'll get netlink events from multipath for any
path-related events.

Not as such. As stated above we should be sending out netlink events for
path up/down events, but to my knowledge no-one is taking advantage
of them. Certainly not udev in its default setting nor multipath.

Cheers,

Hannes
