Sure, --no-floppy would be consistent with the installers, but it will
take some effort to get right.  Let's not forget CD floppy emulation, by
the way.  You wrote that sometimes a hard drive can be reported as a
floppy.  Perhaps we still want to search floppies as the last resort.

Besides, I'd prefer to avoid floppy search is all "search" commands.  I
have a custom rule to boot another distro, and it uses "search" by
label.  I don't want to add --no-floppy to that command because it's an
extra effort.  It's not hard for GRUB to do things nicely without having
users edit their custom rules.

That's why I would prefer optimized search order.  But I'm not strongly
opposing --no-floppy as long as it's done right.

´╗┐We could also start search with the current drive and then go through
the list of other drives, without changing anything else in the order.
Most installations will rely on one disk.  Spinning up more devices
unnecessarily is not nice.
