Upgrading to FreeBSD 5.4

As it turns out, upgrading FreeBSD is not as difficult as I thought it would be.  The process is downright simple for the most part.  The trickiest part is running mergemaster, and upgrading the contents of /etc.  The risk is somewhat mitigated if you backup /etc before you run the mergemaster command.

Here is how I upgraded my system from FreeBSD 5.3.

The first thing to do is to create a file for updating the FreeBSD source tree.  I called this file "standard-supfile", and placed it in /etc.  The file looks like this:

*default host=cvsup2.FreeBSD.org
*default base=/usr
*default prefix=/usr
*default release=cvs tag=RELENG_5_4
*default delete use-rel-suffix
*default compress
src-all

To update the source, run the following command:

onion# cvsup -g -L 2 /etc/standard-supfile

This takes a while, so get some coffee and get to work on that programming project you've been putting off...  Once the source has been updated, it's time to rebuild the system.

onion#  cd /usr/src/sys/i386/conf
onion#  cp -p GENERIC MYKERNAL
onion#  config MYKERNAL; cd ../compile/MYKERNAL; make depend; make;
onion#  make install;
onion#  tar cf /tmp/etc.tar /etc
onion#  mergemaster

I like to make a copy of the GENERIC file, because any changes I may make to it will get wiped out next time I update the source.  By making a copy of the file and adding my changes to the copy, those changes are preserved.

After running mergemaster, reboot and /etc/motd should be updated to display the current version of the system.

Nike Football boots

Adidas F50 boots or soccer boots are the speed offering from Adidas and the football boots to rival Nike's Vapor offerings. But are the Adidas F50 boots all they are built up to be or are they just living off hype? If you are a keen soccer/football player, you will know doubt take your football boots choice very seriously. I know I do! At the beginning of each season I sit down and look at the latest offerings in the football boot market. From Adidas to the new Nike's and Puma's to Lotto's Laceless offering, I have a real good research for the season! Nike Football Boots Now the latest offering from the Adidas F50 range of boots to date, is the infamous "Blue Adidas F50i", the ones that were held up high by the legendary Lionel Messi in the Champions League Final in Rome. Messu, a player about speed and agility must be impressed with the Adidas F50 Well, they do rival the other industry players such as the Nike Vapor range and the Puma V range and are now being worn by many professional players across the globe. These boots are certainly built for speed and with the revolutionary SPRINT SKIN - a single layered PU synthetic material which is thinner and lighter than normal synthetics, this football or soccer boot has the makings of Adidas's FAST BOOT!
