i'm talking about just libexpat.so.0 ... keep the file around long enough to 
update the system

of course it will when you look at core things like openssl, acl, openldap, 
etc...  if you remove anyone one of these packages completely, you risk 
breaking everything (coreutils and many system packages use libacl) or all 
your network capabilities (sshd/ssh no longer usuable; now you require 
on-site service to fix ... hopefully you have packages cached cause wget no 
longer works either)
