The latter approach sounds good to me. The commands have obvious names, 
have sane default behaviour on most distros, can be easily 
overridden/defined if necessary. I'll go with that.
Much better than hooking into all that acpi crap, or an approach that 
would force users to install xen-specific things in a domU for such a 
trivial action.
