udev 175
========
-The default install location moved from /lib/udev to /usr/lib/udev
-to support systems without the / vs. /usr split. --libbexecdir=
-can still be configured to install things to the rootfs.
+The default configure options have changed, packages need to be adapted
+otherwise udev will be installed in /usr. Example configuration options
+are in INSTALL.
-The udevadm tool moved from /sbin to /usr/bin. Some tools expect
-udevadm in 'sbin'. A symlink to udevadm in 'bin' needs to be
-manually created if needed. Alternatively --bindir=/sbin installs
-udevadm in /sbin.
+The default prefix moved from / to /usr to support installations without
+the historic / vs. /usr split.
+
+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.
+
+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.
+
+Firmware is loaded natively by udev now, the external 'firmware' binary
+is no longer used.
+
+All built-in tools can be listed and tested with 'udevadm test-builtin'.
+
+The 'udevadm control --reload-rules' option has been renamed to '--reload'.
+It reloads the kernel module configuration.
The systemd socket files use PassCred=yes, which requires systemd
version 38.
-The blkid tool is no longer called from udev rules. Udev links directly
-to libblkid now.
-
The udev build system only creates a .xz tarball now.
