Possible to pass env vars into chpst without envdir?

I use runit to daemonize my web application, and I'm trying to see if I can have my process managed by sv not have to have a corresponding envdir for its environment variables. I wonder if I can just pass those vars directly into my call to chpst. This is the run file under /etc/service/myapp: #!/bin/sh exec 2>&1 cd /var/www/myapp # what it currently looks like exec chpst -u www-data:www-data /var/www/myapp/myapp # what I'd ideally like to be able to do FOO=bar BAZ=qux exec chpst -u www-data:www-data /var/www/myapp/myapp As I mentioned, chpst also comes with a -e option to pass a directly with environment variables to it, I could use that, but I'm trying to avoid it for simplicity (fewer things to maintain). Is that at all possible? Tips?
