General

emerge subversion
emerge --config dev-util/subversion

create a group for svn

groupadd -g 1010 svngrp

edit /etc/conf.d/svnserve and change the group

#SVNSERVE_USER="apache"
SVNSERVE_GROUP="svngrp"

Start the service and add it to default runlevel

/etc/init.d/svnserve start
rc-update add svnserve default

Setting up access rights

I currently create a new group for each repository and assign users to the group if they need read/write access.

cd /var/svn/
chmod -R 770 repos
chmod -R g+s repos/db
chgrp -R svngrp repos

(svngrp is the group name that I created in /etc/group to hold the svn users)

Edit /etc/groups and add the users to the group svngrp

Edit /var/svn/repos/conf/svnserve.conf (and set the following parameters)

anon-access = read
auth-access = write
password-db = passwd
realm = TTD_SVN

Edit /var/svn/repos/conf/passwd and add the users (see examples)

Setting up SSH access

Users that use the svn need to have ssh access set up correctly to the server. This has to be done by ssh-keys.
