As Hippo is based on GIT, your Central Repository may be multiple hosts, or if you are running a small site, distribute your repository amongst your servers or a workstation.
Installing/configuring the Central Repository involves the following:
We set up a host 'group' for users with read/write access to the Hippo Repository: for our example _hippo.
Members of this group will include all administrators pushing updates to the repositories.
On OpenBSD you will do something such as the below:
# group add _hippo # usermod -G _hippo samt # usermod -G _hippo charlie
