That would make sense to me, but I don't know if it's the only
solution. If you separately ensure that they all have the same
configuration first, you could start them in any order I guess.

Yeah, maybe a section discussing both starting and stopping a whole
cluster would be helpful, but I don't know if I feel like I've thought
about it enough myself. Regarding the HP Service Guard commands that
Ulrich Windl mentioned, the very idea of such commands offends me on
some level but I don't know if I can clearly articulate why. :D
