When running as user_u you should not be creating any files in a directory 
with label sysadm_home_dir_t.  If such file creation was permitted then 
user_t would be able to subvert sysadm_t.

If you login as staff_r:staff_t then you will be able to su to root with 
administrative privs, otherwise not.  This is by design.
