[Justin C. Sherrill]

I was going to put this into the 1.4 version of the src/UPDATING file -
any objections?

+> Upgrading DragonFly from 1.2 to 1.4.
+---------------------
+
+There are 3 extra steps necessary to upgrade from 1.2 to 1.4.
+
+- If you have a customized kernel configuration file, it will need
+this line:
+
+options         COMPAT_DF12
+
+- The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
+Conversion of the existing configuration is performed by commenting out
+any line in /etc/pam.conf that contains "pam_skey.so" and then
+running /etc/pam.d/convert.sh.
+
+- You must reboot the system between the 'make installkernel' and 'make
installworld' steps of the upgrade; the system needs to have a newer
kernel
+running before the new world is installed.
