I recently upgraded my FreeBSD server at home to 6.0-Stable after sticking it through with 5.3 for sometime now.
The upgrade was pretty simple.
*default release=cvs tag=RELENG_5 to *default release=cvs tag=RELENG_6
$> cd /usr/src
$> make update
>>> Running /usr/local/bin/cvsup
Parsing supfile “/usr/sup/stable-supfile”
Connecting to cvsup11.FreeBSD.org
Connected to cvsup11.FreeBSD.org
Server software version: SNAP_16_1h
Negotiating file attribute support
Exchanging collection information
Establishing multiplexed-mode data connection
I then read over /usr/src/UPDATING (… from 5.x-stable or higher to 6.x-stable.) to make sure there was nothing critical which had to be done before upgrading.
$> make buildworld
$> make kernel
Note that I did not specify KERNCONF. This is because I have this variable defined in make.conf along with others. It is highly recommended to reboot into single at this point, but I choose not to. After make kernel, I proceeded with:
$> mergemaster -p
$> make installworld
$> mergemaster -i
before rebooting the machine. After “make installworld” “mergemaster -i” it is essential that the machine is rebooted, otherwise the system will become unstable real quick. I was releived to see the following when the machine started:
