You can't supervise a pipeline per se; you need to supervise both
processes in the pipeline independently, and make sure the pipe isn't
broken when one of them dies.
So, have "exec inotifywait /dev/disk" as foobar/run, and have "exec
automounter.py" as foobar/log/run. This wi

Nope, you only get one integrated pipe, not two. It's a *very*
specific setup (and I've stopped being a fan of it since
I've figured out how to do the same thing for

Is this doable in a way consistent with supervision suites?
Pipelines can form practically indefinite graphs in scope owing to the
nature of fds (modulo process control limitations and space
constraints). You might be interested in pipexec, which expl

Two things:
I'm not at a computer but I'm *pretty* sure exec foo | bar doesn't work
right?
But more importantly, if the python program dies, the inotifywatch will get
a SIGPIPE when it writes and then almost assuredly crash itself. You could
kill the python program and see.

Hi all,
I'm making a thumb drive automounter using inotifywait piped into my
Python program, which detects the proper CREATES and DELETES and
automounts and autoumounts accordingly.
Here's what I thought the run script would look like (runit dialect):
#!/bin/sh
exec /usr/bin/inotifywait /dev/dis
