Thanks - I hadn't seen much about that option before, but it seems to
work nicely.
 yumdownloader opennms\*
puts a copy of all the opennms rpms in the current directory, then
rpm -ihv --relocate /var/opennms=/opt/var/opennms --relocate
/var/log/opennms=/logs/opennnms opennms-1.13.4-1.noarch.rpm
opennms-core-1.13.4-1.noarch.rpm
opennms-webapp-jetty-1.13.4-1.noarch.rpm
puts the logs on the root volume and rrds under /opt, leaving /var for
postgresql.  The target paths were created automatically with the
symlinks in /opt/opennms adjusted accordingly. I'll do my next install
that way and then add my own symlink at /var/log/opennms where I'd
otherwise expect to find the logs.
