OK, so let me get my head round this...

The aim is to keep config files in /etc, but state information 
(supervise) in /var/ somewhere (and logs in /var/log/ somewhere)

Assuming I have the following dirs already created:

/etc/sv
/var/run/sv
/var/log/sv

To create a new service "test" with a log, I can do this:

mkdir -p /etc/sv/test/log
mkdir -p /var/log/sv/test
ln -s ../../../var/run/sv/test /etc/sv/test/supervise
ln -s ../../../../var/run/sv/test/log/ /etc/sv/test/log/supervise
ln -s ../../../../var/log/sv/test /etc/sv/test/log/main

I use a generic log run file, so I can symlink that:

ln -s ../../scripts/generic-log-run /etc/sv/test/log/run

Then, create the service run file, and symlink /etc/sv/test into 
/var/service.

ln -s ../../etc/sv/test /var/service

Hey, cool - that works!

Nice one!
