What is so shocking about flushing away the cache for a

Agreed. However, for format, we have a different issue: if you open an
unformatted floppy the normal way, you might get an unreasonable delay
while the floppy driver is trying to autosense its format (which is
not yet there...). Hence the special open("/dev/fd0", 3) format which
gives back a filedescriptor which is neither readable, nor writable,
but which can still be used for ioctls.

What do you mean by "controller" commands? Personnally, I'd find it
extremely bizarre to read a disk using sysctl or /proc/floppy/rawcmd
