Well, the names have changed a bit ;)  POLICYTYPE is no longer 
operative, so I think
you have booted up in 'targeted' mode, not strict. 'enforcing=0' still 
works for me.

Here is what you need for strict:

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcinfg - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - No SELinux policy is loaded.
SELINUX=enforcing
 
# SELINUXTYPE= can take one of these two values:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=strict
