I don't have a Devuan VM initted by runit, so the following info would
need to be tested by someone who does.
Assuming fio is to be run as root group root, which I infer from your
message, the run script in the service directory looks like the
following:
#!/bin/sh
exec /usr/bin/fio --server
If your --server needs any args, they should appear after --server. DO
NOT use --daemonize in runit: runit handles backgrounding by itself.
Because you don't want this thing to start on boot, place an empty
file called "down" inside the service directory. That way the admin
will need to start up the daemon explicitly.
Like I say, I don't have the setup to test this thing, but it can
probably help somebody who does.
