Description Philip Lawatsch 2005-07-14 13:10:03 UTC
firmware.agent tries to be smarter than usb.agent. usb.agent gets the path sysfs is mounted by staticall using /sys. firmware.agent however does this: SYSFS=$(sed -n 's/^.* \([^ ]*\) sysfs .*$/\1/p' /proc/mounts) This works fine as long as sysfs is mounted only ONCE. If its mounted more than once the variable will contain serveral lines and when used in cp "$FIRMWARE_DIR/$FIRMWARE" $SYSFS/$DEVPATH/data cp will silently fail (.../data is a file, and 2 or more files cant be copied to a file). So either limit the output of $(sed -n 's/^.* \([^ ]*\) sysfs .*$/\1/p' /proc/mounts) to one line (but make sure this directory is accessible) or skip it all together and use /sys statically. The way I encountered the bug was that a genkernel initrd failed to unmount its /sys and thus I had it mounted twice. On my desktop machine I've also got it mounted twice, once in my 64bit system and once in a 32bit chroot. So its not uncommon to have such a situation Reproducible: Always Steps to Reproduce: 1. mkdir /mnt/foobar 2. mount sysfs /mnt/foobar -t sysfs 3. do something which will trigger a firmware upload Actual Results: doesnt work since cp will get passed something like cp "/lib/firmware/something" /sys/$DEVPATH/ /mnt/foobar/$DEVPATH/data Expected Results: limit output to one line, either by setting SYSFS=/sys or by testing each possible line and then using one which will work.

Reopen after you've posted what ebuild and version is this bug about...

Sorry, I though it was clear. Aw, its sys-apps/hotplug-20040923 (which is the latest version)
Comment 3 Jakub Moc (RETIRED) 2007-09-04 00:04:17 UTC
sys-apps/hotplug is useless with any recent udev version, and 2.4 kernels are no longer supported. Unmerge it and move on. WONTFIX.
