Package: udev
Version: 0.114-2
Severity: minor
My notebook has a hot-swappable bay to hold either a battery or a DVD drive.
A change of battery has always been detected, but a change of the DVD
drive has only become possible since Linux 2.6.25. Unfortunately udev
only receives a "change" event and no device is created by default. The
device is only created when booting with the DVD drive plugged in.
Here's a fix (or workaround) which makes people with hot-pluggable
drives happy.
The udev rule:
ACTION=="change", SUBSYSTEM=="platform",
DEVPATH=="/devices/platform/bay.0", RUN="/usr/local/bin/udev-dvdbay.sh"
Contents of the script:
if [ -b /dev/hda ]; then
rm /dev/hda
else
mknod /dev/hda b 3 0
chmod 660 /dev/hda
chgrp cdrom /dev/hda
fi
It'd be nice to see such functionality included in the udev package.
It can surely be done better than I did, without assuming /dev/hda for
example, but at least it works for me now.
