When usb.rc is started by hotplug on system startup, it checks to see if /proc/bus/usb is already mounted by checking for the file /proc/bus/usb/devices. On my system, /proc/bus/usb is mounted by /etc/init.d/localmount right after modprobing for usbcore. This allows the mount to succeed, but the file /proc/bus/usb/devices doesn't exist yet. It only appears after modprobing one of the host controller modules, ehci_hcd in my case. However, the host controller modules are only inserted by usb.rc *after* trying to re-mount /proc/bus/usb, therefore mount gives an error about it already being mounted: mount: usbfs already mounted or /proc/bus/usb busy mount: according to mtab, usbfs is already mounted on /proc/bus/usb The problem is rather cosmetic, as there is no loss of functionality. However, I find it nice not to have any errors on boot ;-) The following patch to usb.rc solves the problem for me: --- usb.rc.orig 2004-07-10 14:12:04.256260496 +0200 +++ usb.rc 2004-07-10 14:24:23.372897688 +0200 @@ -147,7 +147,8 @@ modprobe -q usbcore >/dev/null 2>&1 if [ -d /proc/bus/usb ]; then # if it's not mounted, try to mount it - if [ ! -f /proc/bus/usb/devices ]; then + if [ -z "`grep " /proc/bus/usb " /proc/mounts`" ]; then +# if [ ! -f /proc/bus/usb/devices ]; then if grep -q -E "^[^#][^[:space:]]+[[:space:]]+/proc/bus/usb/?[[:space:]]" /etc/fstab; then mount /proc/bus/usb else Reproducible: Always Steps to Reproduce: # uname -a Linux morpheus 2.6.7-gentoo-r8 #3 Wed Jul 7 02:55:40 CEST 2004 i686 Intel(R) Celeron(R) CPU 1.80GHz GenuineIntel GNU/Linux sys-apps/baselayout-1.9.4-r2 sys-apps/hotplug-20040401
Thanks, this has now been fixed upstream and will show up in the next release (within a day or so.)
