Yes, their number is the same, but I meant the amount of time required. The USB
test cases allowed us to combine them with other test cases (e.g. partitioning)
or perform a minimal install, while the new test case doesn't (a default
install is mandatory).

OK, you're right that there are some cases which could bypass our testing.
That's why I assumed this idea might not fly, even though I'd personally have
no problem to focus on "reasonable coverage" instead of full coverage. But
there might be better approaches to handle this than my "a)" proposal.
From all that you described above, it seems that none of the important features
to be tested should be negatively affected if we allow arbitrary partitioning
or a different package set (provided the default installation source is used).
Or even other, like VNC or basic video mode. What needs to stay fixed is just
the install media + environment + install source. Which essentially my "b)"
proposal in the original email. That would allow us to be more effective when
going through "Default boot and install" table while (hopefully) not
sacrificing any test coverage. What do you think about that?

That would definitely speed things up. But it feels to me a bit ugly to kill
installations during execution as an official test approach. Would the idea
written above serve better? It's not that fast and easy (the installations
should still finish and you should verify the system boots), but since it can
be combined with other test cases, it should not effectively slow us down (too

I'd put "Alpha/Final" into the Milestone in the "Default boot and install"
table. And the testcase would contain an admon bar linking to a Final criterion
saying "installation must work from optical media". That could be obvious
enough (at least for us, initiated testers) and follow the same pattern we use
for other such mixed-milestone test cases. Wdyt?
