Well, I'm inclined to agree, but it seems that digimer's use case is
also valid, and apparently quite widespread (especially for RHEL
users?).

And I certainly don't want to be the one validating configurations like
the one she posted ;-)

Basically, unless we can do this better, having multiple devices per
fence topology level needs to be considered broken and might be better
removed.
