+The default 'configure' install locations have changed. Packages for systems
+with the historic / vs. /usr split need to be adapted, otherwise udev will
+be installed in /usr and not work properly. Example configuration options are
+in INSTALL.
+
+The default install location of the 'udevadm' tool moved from 'sbin'
+to /usr/bin. Some tools expect udevadm in 'sbin'. A symlink to udevadm
+needs to be manually created if needed.
+
+The expected value of '--libexecdir' has changed and must no longer contain
+the 'udev' directory.
+
+Kernel modules are now loaded directly by linking udev to 'libkmod'. The
+'modprobe' tool is no longer executed by udev.
+
+The 'blkid' tool is no longer executed from udev rules. Udev links
+directly to libblkid now.
