I agree with Jens that it's best to leave it to the Linux =

distributors to

select a default I/O scheduler.

That assumes such a thing exists.

Well, as of now the default is more or less in the Schrdinger's cat =
state :)

Metaphors apart, I do agree with your point.  As for me, what you
point out is one of the core issues at stake here.

Thanks,

The kernel knows what devices it is
dealing with. The kernel 'default' ought to be 'whatever is usually =

best

for this device'. A distro cannot just pick a correct single default
because NVME and USB sticks are both normal and rather different in =

needs.
