Hi,
These are some scripts I have written to auto-detect what network card
and cd drive udev rules to use:
cat > detect-cd << "EOF"
#!/bin/bash
# Written by Reece H. Dunn <[EMAIL PROTECTED]>
for block in `find /sys/block -maxdepth 1 -name [sh]d* | sed 's@/sys@@'`; do
udevtest ${block} > tmp/udev-info
if [[ `cat /tmp/udev-info | grep -F "ID_TYPE=cd"` ]]; then
MODEL=`cat /tmp/udev-info | grep -F "ID_MODEL" | sed
"[EMAIL PROTECTED](.*\)'@\1@"`
REVISION=`cat /tmp/udev-info | grep -F "ID_REVISION" | sed
"[EMAIL PROTECTED](.*\)'@\1@"`
echo "SUBSYSTEM==\"block\", ENV{ID_MODEL}==\"${MODEL}\",
ENV{ID_REVISION==\"${REVISION}\", SYMLINK+=\"cdrom dvd\"}"
fi
rm /tmp/udev-info
done
EOF
cat > detect-net << "EOF"
#!/bin/bash
# Written by Reece H. Dunn <[EMAIL PROTECTED]>
for net in `grep -H . /sys/class/net/*/address | sed -e
'/:00:00:00:00:00:00/d'`; do
address=`echo $net | sed -e '[EMAIL PROTECTED]:\(.*\)@\1@'`
name=`echo $net | sed -e '[EMAIL PROTECTED]/\(.*\)/[EMAIL PROTECTED]@'`
echo "ACTION==\"add\", SUBSYSTEM==\"net\",
SYSFS{address}==\"${address}\", NAME=\"${name}\""
done
EOF
These can then be used like this:
./detect-cd > /etc/udev/rules.d/82-cdrom.rules
./detect-net > /etc/udev/rules.d/26-network.rules
The detect-cd script will only work properly with machines that only
have one CD, as it always uses the same symlink for the CD devices.
Are these useful to include in the LFS book?
