You could use `s6-rc -a list`, perhaps? It lists all services that are in the active state.

For example, I have a oneshot service called `swap` that turns on or off swap volumes.

# s6-rc -a list | grep swap
swap
# s6-rc stop swap
# s6-rc -a list | grep swap
#

I could run `grep -q swap` and then the exit status would tell me if it's running or not.

Does that give you what you want?
