+Reboot and poweroff
+-------------------
 
-Using finit with alternative systems
-------------------------------------
+Stock reboot and poweroff utilities of a modern Linux distribution may not
+work correctly with finit. You can replace them with simple scripts that
+send SIGUSR1 to finit for reboot, SIGUSR2 for poweroff.
 
-Currently tested only with Mandriva 2008. Proceed with caution, there are
-problems related to udev and pam.
 
-1 - Add init=/sbin/finit-mdv to the kernel boot line
+Using finit with KDE
+--------------------
 
-2 - Provide a suitable /usr/sbin/services.sh, this is the one I use in my
-    test system:
-
-    mkdir /var/lock/subsys
-    chmod 1777 /var/lock/subsys
-    /etc/init.d/network start
-    dhclient eth0
-    /sbin/start_udev&
-    /etc/init.d/portmap start
-    /etc/init.d/nfs-common start
-
-3 - Provide /etc/hostname if you don't have it already
-
-4 - Set the pointer device in the X server configuration to /dev/input/mice
+If you use finit to start KDE with auto-login enabled, hal-based device
+automounting may not work correctly. That happens because the session
+is started before the system message bus, so add a "dcop kded mediamanager
+reloadBackends" call in the user AutoStart to restart the client.
