It is the same path perf tool is taking - see first paragraph:
https://lore.kernel.org/r/YtQM40VmiLTkPND2@kernel.org
I don't want to deal with the regular breakages or hacks to
boot/compressed/ just because little duplication. We copy the header
once and that's it - it doesn't even have to get updated like perf tool
does from time to time.
