Nothing. It's IDE Floppy, not Floppy. You should have new hd* entries
in /dev for your IDE Floppy device. Read some more lines in your
dmesg output.
Is this another change introduced by libata?
No. IDE floppies are a different kind of device, IOmega Zip is one example.
They are attached to an IDE controller, just like a hard disk or CDRom
drive.
RHEL still uses /dev/fd{0,1} so I imagine this is a back-port they have
done?
Dunno. The kernel driver still uses fd internally. However, here's the
relevant udev rules from Gentoo:
% grep -r floppy /etc/udev/rules.d
/etc/udev/rules.d/50-udev.rules:# floppy devices
/etc/udev/rules.d/50-udev.rules:KERNEL==fd[0-9]*, NAME=floppy/%k,
SYMLINK+=%k, GROUP=floppy
/etc/udev/rules.d/50-udev.rules:KERNEL==fd[0-9]*, ACTION==add,
ATTRS{cmos}==*, RUN+=create_floppy_devices -c -t $attr{cmos} -m %M -M
0660 -G floppy $root/floppy/%k
/etc/udev/rules.d/50-udev.rules:KERNEL==fd[0-9]*, ACTION==remove,
RUN+=/bin/sh -c 'rm -f $root/floppy/%k?*'
/etc/udev/rules.d/50-udev-default.rules:KERNEL==hd*, SUBSYSTEMS==ide,
ATTRS{media}==floppy, OPTIONS+=all_partitions
/etc/udev/rules.d/50-udev-default.rules:KERNEL==fd[0-9],
GROUP=floppy
/etc/udev/rules.d/50-udev-default.rules:KERNEL==fd[0-9], ACTION==add,
ATTRS{cmos}==?*, RUN+=create_floppy_devices -c -t $attr{cmos} -m %M -M
0640 -G floppy $root/%k
But the rule for IDE floppy looks like this:
% grep -r ide-floppy /etc/udev/rules.d
/etc/udev/rules.d/60-persistent-storage.rules:KERNEL==hd*[!0-9],
ATTR{removable}==1, DRIVERS==ide-cs|ide-floppy,
GOTO=persistent_storage_end
Bye...
