From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem, from rc.sysinit: # Mount /proc and /sys (done here so volume labels can work with fsck) mount -n -t proc /proc /proc [ -d /proc/bus/usb ] && mount -n -t usbfs /proc/bus/usb /proc/bus/usb This assumes the mount point /proc/bus/usb is there. If it is not there usbfs won't be mounted and bad things happen later. For example kudzu loses all your USB devices. In RH kernels the mount point is always there since usb-core is always built-in in order to support boot from USB file systems. If you are not booting from a USB file system usb-core works fine as a module. rc.sysinit needs to make sure this module is loaded before trying to mount usbfs.
This is just adding redundant modprobe calls that will only slow down the default case (albeit not much); that's not really a *good* solution.
There is already a test to see if the directory is there. Only do the mod probe if it is missing.
Actually.... usb-core will get loaded if the host controller is loaded, right? So, what's needed is to simply add a dev.d entry for usbcore that mounts usbfs.
Another way is for the installer to add a line to fstab. All of these are minor fixes for the problem once you figure out what is going on. The problem here is that doing something simple like making usb-core a module causes a hard to diagnose failure in FC3. A root part of this is from kudzu using /proc/bus/xxx instead of /sys
This was fixed in a later build.
