I have djbdns running under runit on my workstation.  I installed the
programs in /usr/sbin.  I created a new user (dnscache) and group (dns)
and ran:

dnscache-config dnscache root /etc/dnscache

to create the /etc/dnscache service directory, and then re-wrote the
service directory like this:

run:
#!/bin/sh
# link stdout and stderr, so they both get logged
exec 2>&1
# put the file seed on the stdin file descriptor, so that dnscache can
# read it
exec <seed
# run dnscache with the envars in ./env
exec chpst -e ./env /usr/sbin/dnscache

log/run:
#!/bin/sh
exec svlogd -tt /var/log/dnscache

Note that I'm running the logging process as root.  I added GID and UID
files to the env directory.  This sacrifices a couple of the limits that
DJB's scripts uses, but these could be added back using chpst options, I
just haven't got round to it yet.

It works well for me.
