Should they be sorted by created_at date?

[ranjan]

It should be sorted by hostname.

@ranjan Thanks! Please add a test for this. About the ordering, I think that's highly subjective, I'd prefer them to be ordered by last report - why do you say it should be sorted by hostname?

[domcleal]

@dLobatog note that the active list already is sorted by hostname (@host/host_data)

[ranjan]

[test] failure looks unrelated to the change

Merged as cce6720, thanks @ranjan!
