+Usual options for udev installed in the root filesystem are:
+  ./configure \
+    --prefix=/usr \
+    --sysconfdir=/etc \
+    --sbindir=/sbin \
+    --libdir=/usr/lib64 \
+    --with-rootlibdir=/lib64 \
+    --libexecdir=/lib/udev \
     --with-selinux
-        link against SELInux libraries to set the expected context
-        for created files
 
-The installation directories are controlled by $prefix, $exec_prefix
-$sysconfdir and $libdir-name. Documentation, development files are
-installed below $prefix, binaries are installed below $exec_prefix,
-libraries below $exec_prefix/$libdir-name.
+All options:
+  --prefix=
+      Usually /usr, prefix for man pages, include files.
+  --sysconfdir=
+      Usually /etc.
+  --sbindir=
+      Usually /sbin, the place for udevd and udevadm.
+  --libexecdir=
+      Usually /lib/udev, the udev private directory.
+  --enable-debug
+      Compile-in verbose debug messages. Usually not needed,
+      it increases the size of the binaries.
+  --disable-logging
+      Disable all logging and compile-out all log strings. This
+      is not recommended, as it makes it almost impossible to debug
+      udev in the running system.
+  --with-selinux
+      Link against SELinux libraries to set the expected context
+      for created files.
+  --disable-extras
+      Disable the build of all extras which have larger external
+      dependencies like glib, libacl, libusb, ...

-The well defined location for scripts and binaries which are called
-from rules is /lib/udev/ on all systems and architectures, anything
-else is broken. Other packages who use udev, may use the /lib/udev/
-directory to install their rule helper and udev rule files.

 It is recommended to use the /lib/udev/devices/ directory to place
 device nodes, directories and symlinks, which are copied to /dev/
