Actually I did this:
sudo mv /var/lib/svn/* /home/user/data
This leaves an empty /var/lib/svn directory ready to mount into.

This worked fine to let the moved files wind up back where they were before but
now not using up / space.

sudo systemctl start apache2

After this procedure my system does no longer complain about no disk space and
the subversion server is accessible like before via the web interface.
