If you just want security updates and no other changes, you'd update against RELENG_7_2 instead.


Here are you referring only to security updates to the "core OS" and not applications in "ports" such as Firefox?

That's right, yes.

In the BSDs, the baseline or core OS is separate from installed ports or packages, and is updated separately from them.

What's an example of something that is in "the core OS" and not in the "ports"? GCC? the shells? the kernel?

Yes, all of the above. Basically, ports (or packages) install under / usr/local; everything else under /bin, /usr/bin, etc is part of the core OS.

However, if you wanted to install another version of GCC, you could have both the one which comes with the system and a port version present. Likewise for things like sendmail, BIND, openssl, and so forth which normally come with the core OS, but may not be updated as rapidly as the version in ports is.
