 ### Umount Module
 #
 # This module represents the last part of the installation, the unmounting
-# of partitions used for the install.  It is also the last place where it
+# of partitions used for the install.  After this, there is no regular way
-# is possible to copy files to the target system.
+# to modify the target system anymore.

-# The "copy log files" functionality is deprecated; use the *preservefiles*
-# module instead, which is more flexible.
-#
-# This module has two deprecated configuration keys:
-#   srcLog  location in the live system where the log is
-#   destLog location in the target system to copy the log
