sysadm_t domain (the default domain for sysadm_r role) has access to almost 
everything on the system.  sysadm_t can run fdisk, useradd, vipw, etc.

You can't realistically deny sysadm_t access to any resource without 
significant changes to the entire policy (such things have been discussed but 
are a long way from being implemented).

You can deny the root user sysadm_r role to deny them such access (but make 
sure you grant another user sysadm_r so that you can still administer your 
system).
