+# This is here to serve as a note to myself, and future developers.
+#
+# Any Display manager (gdm,kdm,xdm) has the following problem:  if
+# it is started before any getty, and no vt is specified, it will
+# usually run on vt2.  When the getty on vt2 then starts, and the
+# DM is already started, the getty will take control of the keyboard,
+# leaving us with a "dead" keyboard.
+#
+# Resolution: add the following line to /etc/inittab
+#
+#  x:a:once:/usr/bin/startDM
+#
+# and have /usr/bin/startDM start the DM in daemon mode if
+# a lock is present (with the info of what DM should be started),
+# else just fall through.
+#
+# How this basically works, is the "a" runlevel is a additional
+# runlevel that you can use to fork processes with init, but the
+# runlevel never gets changed to this runlevel. Along with the "a"
+# runlevel, the "once" key word means that startDM will only be
+# run when we specify it to run, thus eliminating respawning
+# startDM when "display-manager" is not added to the default 
+# runlevel, as was done previously.
+#
+# This script then just calls "telinit a", and init will run
+# /usr/bin/startDM after the current runlevel completes (this
+# script should only be added to the actual runlevel the user is
+# using).
