Description of problem:
Booting from the FC3-i386.iso DVD image, on a system with no floppy controller, I still get the messages:
<6>inserting floppy driver for 2.6.9-1.667
<4>Using cfq io scheduler
<6>Floppy drive(s): fd0 is 1.44M
<4>floppy0: no floppy controllers found
even though I had booted with "linux nofloppy ..."
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot w/ linux nofloppy on an NX1750S mini-ITX board
2. look at vty4
at a guess, the initrd scripts are loading it unconditionally.

Suggested fix, gleaned from looking at how "nomodules" works.
I'm not seeing what the bug is. Have we documented "nofloppy" somewhere?
Regarding the patch, if you're booting from the CD, then changing rc.sysinit
won't help any, as the install CDs don't use the init system that an installed
system would. Also, rc.sysinit isn't part of the initrd even on an installed
Googling "linux nofloppy" showed that nofloppy is a known boot argument, though
you're right, it isn't clear if it's formally documented anywhere.
That notwithstanding, floppy-less computers are more and more common (such as
laptops and mini-ITX computers).
Being able to control the (currently) unconditional loading of the floppy
driver, which will then fail, is a win, since it cuts down an error message on a
condition that isn't actually an error. That is, if you don't have a floppy
drive and you know this, then generating an error message when the floppy module
fails to load is hardly useful or informative.
But more to your point... Where then does the floppy driver get loaded if not
in /etc/rc.d/rc.sysinit? I'm talking about an installed system in this case.
On the installed system, yes, rc.sysinit. But the log you pasted is from anaconda.
Is there actually an error message? I don't really care about this message
showing up on tty4; it makes absolutely no difference.
I think you've just stumbled across some incorrect advice on the net.
Ok, so how do we fix it both on a running system and in Anaconda so that you can
avoid probing for the floppy drive? On systems (especially prototype systems,
where you are trying to bring up new hardware and probing for devices might
cause instabilities) you might need a way to inhibit probing for a floppy drive.
install floppy /bin/true
in /etc/modprobe.conf will fix it for the installed system; there won't be any
separate handling of it for rc.sysinit.
