"sv down foo" => kill -SIGQUIT?

"sv down foo" => kill -SIGQUIT?

[Adam Megacz]

I just discovered (or was pointed to) runit.  It rocks.

However, I have one service (OpenAFS's fileserver) that needs to be
sent a SIGQUIT as the way of telling it to shut down gracefully.
Sending a SIGTERM causes it to simply quit immediately, and the next
time it starts up it has to do a sort of psuedo-fsck scan of its
files, which can take around an hour in some cases.

Is there any way to tell runit that this process wants to be sent a
SIGQUIT rather than SIGTERM?  I know about "sv quit foo", but I'm
worried I'll accidentally type "sv down foo".

Thanks,

Check runsv manual page, 'CUSTOMIZE CONTROL' section.

Perfect!  Thanks!  I'd like to contribute the following configuration
to handle the OpenAFS server suite (openafs.org)

/var/service/afs-server/run

  #!/bin/bash
  exec /usr/sbin/bosserver -nofork

/var/service/afs-server/control/t

  #!/bin/bash
  sv quit afs-server

Bosserver really needs to be sent SIGQUIT; if you sent it SIGTERM it
will die but leave its child processes running (orphaned), at which
point they're difficult to easily shut down cleanly.

You might want to consider adding this here in case other people don't
know about the SIGQUIT thing (it took me a while to figure it out).

Thanks again; runit is great!
