Since 2.0 (I think), the 'members' line is optional. However, hostgroups 
still need to *have* members. The reason the 'members' line is optional 
is the introduction of the 'hostgroups' variable in the host object 
definition.

So, unless at least one of your hosts have a line saying

"hostgroups  your-hostgroup-name"

you *do* need the 'members' line.
