Draft Version of New Keeping FreeBSD Up-To-Date

Four years ago I wrote an article titled Keeping FreeBSD Up-To-Date. The goal was to document various ways that a FreeBSD 5.2 system could be updated and upgraded using tools from that time, in an example-drive way that complemented the FreeBSD Handbook.

I decided to write an updated version that starts with a FreeBSD 7.1 RELEASE system and ends by running FreeBSD 7.2-STABLE. Sections include:

Sections:
---------
Introduction
FreeBSD Handbook
The Short Answer
Understanding FreeBSD Versions
Learning About Security Issues
Starting with the Installation
Installing Gnupg and Importing Keys
Installing Source Code
Installing CVSup
Applying Kernel Patches Manually 
Applying Userland Patches Manually
Using CVSup to Apply Patches
Using Csup to Apply Patches
FreeBSD Update to Upgrade FreeBSD within Versions
STABLE: The End of the Line for a Single Version
What Comes Next?
Conclusion

Looking at the sections, I noted that it might be good to add a section on using FreeBSD Update to upgrade to 8.0, assuming you're starting with a non-7.2-STABLE system. From what I've read, that isn't possible? (Anyone know for sure?)

It would also be nice to publish the final version once 8.0 is RELEASEd so I could incorporate that.

If you'd like to read the document and provide feedback, I'd appreciate constructive comments. The draft is available as a .pdf at http://www.taosecurity.com/kfbutd7.pdf. Thank you.
