John Wendel asked:
I need to connect a usb card reader that has a device driver that only works with a 2.4 kernel (like RH9). Before I go to the trouble of downloading, configuring, flailing, has anyone ever run a 2.4 kernel on an FC3 system? Will the hotplug stuff work? How about udev?

FC3 takes more advantage of 2.6 (than FC2 did): as John thought, udev and hotplug rely on the /sys work that was done during 2.5 development. (And that work was largely responsible for the change in ABI that means the original device driver won't work in 2.6)...
You probably could get something working with a static /dev and manually configuring stuff that FC3 normally leaves to hotplug. But it wouldn't be a standard FC3, and you'd have to be very careful while upgrading.
Hint: on the fedora-devel or fedora-test list recently, it was pointed out that chattr +i $filename will stop practically *anything* upgrading that file!

Thanks for the tips! Not what I wanted to hear, but I figured the /dev issue would be a PITA. Maybe I'll have to convert my old play box to RH9, I don't think I'm up for the challenge.
Regards,
John
