   recommend to replace a distro's udev installation with the upstream version.
 
 Requirements:
-  - Version 2.6.18 of the Linux kernel for reliable operation of this release of
-    udev. The kernel may have a requirement on udev too, see Documentation/Changes
-    in the kernel source tree for the actual dependency.
+  - Version 2.6.22 of the Linux kernel for reliable operation of this release of
+    udev. The kernel must not use the CONFIG_SYSFS_DEPRECATED* option.
 
   - The kernel must have sysfs, unix domain sockets and networking enabled.
-    (unix domain sockets (CONFIG_UNIX) as a loadable kernel module may work,
-    but it does not make any sense - don't complain if anything goes wrong.)
+    Unix domain sockets (CONFIG_UNIX) as a loadable kernel module is not
+    supported.
 
   - The proc filesystem must be mounted on /proc/, the sysfs filesystem must
     be mounted at /sys/. No other locations are supported by udev.
 
+  - The system must have the following group names resolvable at udev startup:
+      disk, cdrom, floppy, tape, audio, video, lp, tty, dialout, kmem.
+    Especially in LDAP setups, it is required, that getgrnam() is able to resolve
+    these group names with only the rootfs mounted, and while no network is
+    available.
 
 Operation:
   Udev creates and removes device nodes in /dev/, based on events the kernel
