Dude, it's not cool to cause users' machine to fail boot because you
want bug report. You don't do that. There are other ways to achieve
that. When the kernel can't make all hotpluggable nodes hotpluggable
(I mean, it's not necessarily node aligned to begin with), generate
warning and a debug dump with appropriate log levels.
If you think causing users' machine fail boot indetermistically is
acceptable, you really shouldn't be maintaining anything. What is
this? Are you nuts?
This is doubly idiotic because this is all early boot. Most users
don't even have a way to access the debug info if the machine crashes
that early. Developement convenience is something that we consider
too but, seriously, users come first. This is not your personal
playground. Don't frigging crash if you have any other option.
Again, the best depend on the purpose and the goal. If someone specify
to enable hotplugging, They are sure they need it. Now, any fallback
achieve their goal. Their goal is not booting. If they don't have enough
machine to achieve their goal, we have only one way, tell them that.
If we had an alternative way, I might say an another answer.
