-Read the README file for how to install udev.
+The options used used usually look like:
+  %configure \
+    --prefix=/usr \
+    --sysconfdir=/etc \
+    --bindir=/usr/bin \
+    --libdir=/usr/lib64 \
+    --libexecdir=/usr/lib/udev \
+    --with-systemdsystemunitdir=/usr/lib/systemd/system \
+    --with-selinux
+
+The options used in a RPM spec file look like:
+  %configure \
+    --prefix=%{_prefix} \
+    --sysconfdir=%{_sysconfdir} \
+    --bindir=%{_bindir} \
+    --libdir=%{_libdir} \
+    --libexecdir=%{_prefix}/lib/udev \
+    --with-systemdsystemunitdir=%{_prefix}/lib/systemd/system \
+    --with-selinux
+
+The options to install udev in the rootfs instead of /usr,
+and udevadm in /sbin:
+    --bindir=/sbin
+    --libexecdir=/lib/udev
+    --with-systemdsystemunitdir=/lib/systemd/system
+    --with-rootlibdir=/lib64
+
+Some tools expect udevadm in 'sbin'. A symlink to udevadm in 'bin'
+needs to be manually created if needed.
+
+The defined location for scripts and binaries which are called
+from rules is /usr/lib/udev/ on all systems and architectures. Any
+other location will break other packages, who rightfully expect
+the /usr/lib/udev/ directory, to install their rule helper and udev
+rule files.
+
+It is possible to use the /usr/lib/udev/devices/ directory to place
+device nodes, directories and symlinks, which are copied to /dev/
+at every bootup. That way, nodes for devices which can not be
+detected automatically, or are activated on-demand by opening the
+pre-existing device node, will be available.
+
+Default udev rules and persistent device naming rules may be required
+by other software that depends on the data udev collects from the
+devices.
