post-start failure

[Frew Schmidt]

Hello All!

I have created a number of post-start scripts to verify that our
servers have successfully started; they tend to look something like
this:

   post-start script
     wget http://127.0.0.1:9200/ \
       --retry-connrefused       \
       -O /dev/null              \
       --tries 30                \
       --waitretry 1
   end script

This correctly blocks until the server is accessible.  The frustrating
thing is that if a server is running, but hung or something, this
script will exit non-zero, yet the server will still be considered up.
Is there a pattern to have the post-start script be what I want, where
a non-zero exit stops the service and marks it as failed?

Thanks

(PS: please do not remove me from the To/CC headers, I am not
