+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
-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-rule_generator
+ Disable persistent network, cdrom naming support.
+ --disable-hwdb
+ Disable hardware database support
+ --disable-udev_acl
+ Disable local user acl permissions support.
+ --disable-gudev
+ Disable Gobject libudev support.
+ --disable-keymap
+ Disable keymap fixup support.
+ --enable-floppy
+ Enable legacy floppy support.
+ --enable-edd
+ Enable disk edd support.
+ --enable-action_modeswitch
+ Enable action modeswitch support.

pre-existing device node, will be available.
