# Make sure any new files created in /etc, which are not managed by installf, 
# are created with a secure access mask.  Using chmod is problematice, since 
# that would also change the rights of any existing file, and we are only 
# interested in setting the rights for new files.
#
# The bug here is that these files should be managed by installf and hence
# have explicit ownership and permissions.  However, since there is only
# one user (root) under which this file can be executed, that enhancement
# is left for the future.  Until then, the only consequence is that these
# files won't be removed when they should be.
