Remove firewalld; install iptables.  Problem solved.  This has been
discussed ad nauseum on this list recently.

Not RedHat specific issues; that's just progress from upstream.

This one _is_ nasty; it means you didn't properly use upstart in RH6,
but then again who did?  We all stuck with standard init scripts :-)

Only a default; sendmail is still there to install if you need it.

You've misunderstood kernel support and "type" support.  We've had 64bit
filesizes for many years on 32bit kernels.  Changing time_t to 64bits
is independent of the hardware being 32 or 64 bit.

Basically, RHEL is Enterprise (the E); very very few enterprises have
32bit machines any more.
