# When a package is upgraded, there may be some shared
# libs that are leftover by the previous package.
# It is not feasible to remove these libs while the system
# is up and running since some running program may have loaded the
# lib in memory and it may cause problems for the application.
# The safest way to delete the file is when the system is being
# booted up.
# This script creates a file of all libs that need to be cleaned.
# On bootup, the bootscript checks the file and cleans the files
# indicated in the list.
