-Usual options for udev installed in the root filesystem are:
-  ./configure \
+The options used used usually look like:
+  %configure \
     --prefix=/usr \
     --sysconfdir=/etc \
-    --sbindir=/sbin \
+    --bindir=/usr/bin \
     --libdir=/usr/lib64 \

+    --with-systemdsystemunitdir=/usr/lib/systemd/system \
     --with-selinux
 
-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, ...
