The rest of the actions run in the foreground [*] together with the
daemon handled by runit:

exec /sbin/vdevd -f -c /etc/vdev/vdevd.conf /dev

ending up at the line nº525 of linux.c:

https://github.com/jcnelson/vdev/blob/master/vdevd/os/linux.c
<https://github.com/jcnelson/vdev/blob/master/vdevd/os/linux.c>

and remaining in waiting for possible events on a file descriptor (like
USB connections).

Cheers,

Aitor.

[*] The binary that is being called in the run script handled by runit
(vdevd in our case)
should run in the foreground, and it should be run without spawning a
new process or a shell.
This point explains the use of the builtin *exec* command.
