The Udev package contains programs for dynamic creation of device nodes.

Approximate build time: 0.2 SBU

Required disk space: 5.2 MB

Udev installation depends on: Coreutils and Make

5.35.1. Installation of Udev

The udevstart program hardcodes the path to the udev program in itself, which would cause issues since udev was installed in a non-standard location. Fix this by running the following:

sed -i 's@/sbin/udev@/tools/sbin/udev@g' udevstart.c

Also, ensure that udev knows the correct location to look for its configuration files:

sed -i 's@/etc@/tools/etc@g' etc/udev/udev.conf.in

Now compile Udev:

make prefix=/tools etcdir=/tools/etc

This package does not come with a test suite.

Install the package:

make DESTDIR=/tools udevdir=/dev install

Udev's configuration is far from ideal by default, so install LFS-specific configuration files here:

cp ../udev-config-2.permissions \
    /tools/etc/udev/permissions.d/00-lfs.permissions
cp ../udev-config-1.rules /tools/etc/udev/rules.d/00-lfs.rules

Details on this package are located in Section 6.57.2, “Contents of Udev.”
