FreeBSD: How To Upgrade FreeBSD 7 to 8 Stable Release
FreeBSD 7.x allows upgrade of existing installation to FreeBSD 8.0-STABLE. Since this is a major version upgrade, it is recommended that you backup your data, database and configuration files.
This guide will walk a user through updating his source to follow FreeBSD's stable branch. Please make a full backup of the current system before following this guide.
STEP 1: Syncing the source tree
- cvsup installation and configuration
# cd /usr/ports/net/cvsup-without-gui
# make install clean
OR
# pkg_add -r cvsup-without-gui
Copy the sample supfile for Stable to /usr/local/etc/stable-supfile:
# cp /usr/share/examples/cvsup/stable-supfile /usr/local/etc/
Edit file and set host name which specifies the server host which will supply the file updates to your system.
*default host=cvsup1.us.FreeBSD.org
Set release tag to stable 8:
*default release=cvs tag=RELENG_8
Run cvsup to download the latest stable source:
# cvsup -L 2 /usr/local/etc/stable-supfile
When the cvsup has completed, change to the /usr/src directory

FreeBSD: How To boot kernel.old
If you want to boot with an old kernel, because the current one is not working properly, this is what you have to do:
During boot you get a message like:
"Booting kernel in 10 seconds or press enter..."
Just hit any key except the ENTER key and you'll get a prompt.
Type 'unload all' and then 'boot [kernel file]' where [kernel file] is the kernel you want
to boot e.g. 'kernel.old' .
Your FreeBSD machine will boot with the kernel you specified.

Google acquires Aardvark
When you need an answer to a very specific question, sometimes the information just isn't online in one simple place. For example, let's say you want to know if there's snow on Skyline Boulevard on a given day or the best time of year to plant beans in the Bay Area. You might find weather reports and planting guides on many different sites, but for these kinds of questions, a person with the right expertise can be a lot more useful than a webpage.
