Upgrading DragonFlyBSD

I always forget how to do this, so I'm documenting it here. The DragonFlyBSD website is quite good and this all comes from www.dragonflybsd.org/docs/newhandbook/Upgrading

Firstly, make sure the Makefile is present:

# cd /usr
# make src-create

and wait while it does it's thing.

Then we need to get the new source to build it:

# cd /usr/src
# git checkout DragonFlyBSD_RELEASE_3_8 (which is the current one)

To find out what the current one is:

# cd /usr/srv
# git pull
# git branch -r

Then the build and upgrade process:

# cd /usr/src
# make buildworld
# make buildkernel
# make installkernel
# make install world
# make upgrade
# reboot

And it should all be done.
