 # Plymouth Configuration Module

+#
 # This module can be used to setup the default plymouth theme to 
 # be used with your distribution

-# Only set your theme with this module if you are not doing it 
-# already in your operating systems build configurations. 
-
+#
 # You should only use this module if the plymouth package is installed 
 # on the build configurations of your distribution & the plymouth 
-# theme you want to configure is installed as well. 
+# theme you want to configure is installed as well. If the unpacked
+# filesystem configures a plymouth theme already, there is no need
+# to change it here.

+# Debian / Ubuntu comes with themes "joy", "script", "softwaves",
+# possibly others. Look in /usr/share/plymouth/themes for more.

+# Specifying a non-existent theme will leave the plymouth
+# configuration set to that theme. It is up to plymouth to
+# deal with that.

-# If yours is a debian/ubuntu derived distribution, 
-# following are some example plymouth_theme values that might work
-# plymouth_theme: joy 
-# plymouth_theme: script  
-# plymouth_theme: softwaves
 
-# For other distributions you can look under the themes folder for plymouth, 
-# which is usually /usr/share/plymouth/themes and supply any of theme names 
-# from there to plymouth_theme 
 
-# If the plymouth_theme value is left empty or with a theme name which does not exists. 
-# The module would still look for the theme name for availability in plymouth themes folder. 
-# and as theme will not be found, it will leave the plymouth settings unchanged.
