I'm not sure about this. Are there zero valid use cases for using
multipath without multipathd? On production systems, I agree,
multipathd should always be running. Personally wouldn't want to see
this warning every time I run "multipath" while multipathd is
(temporarily) disabled. Have you got user requests for this feature?

In particular, I dislike the idea of putting this code into
libmultipath. I would love to get rid of the "is_daemon" logic some
day. If at all, the detection of the situation and the warning should
be implemented in multipath, IMO.

The message should be prefixed with the word "Warning: " to make sure
the admin understands that he's supposed to take action.

Regards,
Martin
