A supervise-like tool that's a bit more flexible and didn't
need svscan (you'd start and stop it by hand) or svc (make it respond
properly to SIGTERM, SIGHUP etc., and write the supervisor's PID to a
pidfile). You could even do svscan-style logging by having, say, a
-e switch that made it redirect its child's stderr to its
stdout, and then just piping the output to another instance of
it. There's probably no need for supervise's "down" functionality --
if you don't want the child running, then don't run the supervisor. An
option to specify the delay in seconds before restarting the child
would be useful.
Implemented; see batvise. I've gone back to freedt since, to avoid the huge trees of do-very-little processes this method required.
