I had in mind two livepatches with a dependency on each other that would utilize different callback mechanism. Say the first one just modifies xen_extra_function to print based on a string variable. Applying it would change extra version to say 'FIRST_LIVEPATCH' or such. The second one has an apply and revert callback that modifies the xen_extra_function to print say 'SECOND_LIVEPATCH' and also 'SECOND_REVERTED' when reverted? So you would have: xen-livepatch apply xen_first xl version |grep extra_version [should have FIRST_LIVEPATCH] xen-livepatch apply xen_second xl version |grep extra_version [should have SECOND_LIVEPATCH] xen-livepatch revert xen_second xl version |grep extra_version [should have SECOND_REVERTED] or such? Just want to make sure that the code that is doing the various combinations of callbacks is behaving correctly. Naturally doing all of them would be rather difficult, so I would rather test the most common use-case.
