Updating freenet is a simple as downloading a new .jar file. Updating GNUnet 
is not nearly so easy; stuff has to get recompiled, configuration files get 
changed, and database updates are sometimes necessary. All in all, the Gentoo 
devs have done a remarkable job at keeping the ebuilds working - and they 
typically get new releases of GNUnet into portage within a couple of days!

Unfortunately, portage is not very good at doing CVS. Since I try to help out 
the GNUnet devs by applying CVS patches, etc., I have a script that I use to 
more or less automatically update GNUnet on my machine. Judging by the number 
of times I've lost my entire database or crashed my computer do to careless 
errors relating to this script, I suggest you think very hard before 
implementing it.

In my setup, GNUnet has its own user and its own group. All files to be shared 
are placed under the GNUnet group; the theory being that a renegade gnunetd 
can't trash my entire system. You will have to run the install script as 
root, or modify it to be run some other way. The /etc/init.d script works, 
but rc-update doesn't seem to work on it, so you'll have to invoke GNUnet 
manually every reboot (for example, add it to /etc/conf.d/local.start).

Here is gnunetinstall.sh:
---------------------------------------
#!/bin/sh

cd /root
echo Removing old GNUnet source directory...
rm -R GNUnet
echo Authenticating to CVS server, please press ENTER
cvs -d :pserver:address@hidden:/var/cvs/GNUnet login
echo Authenticated. Downloading sources...
cvs -d :pserver:address@hidden:/var/cvs/GNUnet checkout GNUnet
echo Setting permissions...
cd GNUnet
chmod u+x bootstrap
echo Creating scripts...
./bootstrap
echo Configuring...
./configure --with-crypto=/usr
echo Building GNUnet...
make && echo "Installing GNUnet..." && make install && echo " done."
---------------------------------------

And /etc/init.d/gnunet (somewhat blindly adapted from the original Gentoo init 
script):
---------------------------------------
#!/bin/sh
#
# GNUnet         Start/Stop GNUnet server
#

start() {
        ebegin "Starting GNUnet"
        /usr/local/bin/gnunetd --user=gnunet --config=/etc/gnunet.conf
        eend $?
}

stop() {

        start
        ;;
  condrestart)
        if [ -f /var/lock/subsys/gnunetd ]; then

        ;;

echo  $"Usage: $0 {start|stop|status|restart|reload|condrestart}"
        exit 1
esac

Remember, if you use this stuff and something breaks, I told you not to do it. 
Good luck!
