Puppet users - Dec 2010 - How to show a custom message during a puppet run (at certain conditions)

Hi Puppet Masters,
I''ve a small problem that would like to solve in a somehow elegant
way.
I need to install the oci8 module for php without using a pre-made
package.
The operation involves installing the Oracle client (already done via
Puppet), setting Oracle environments (already done via Puppet),
installing various php modules and components (done) and executing a
command that promtps the user for some data (more precisely the
command "pecl install oci8" and then, when prompted, the user has to
type something like "instantclient,/opt/instantclient_11_2".

Now, please, don''t tell me that I should make a php-oci8 package and
distribute it, I know that.

Sadly I haven''t found a way to provide what is prompted as an argument
to the pecl command and I don''t know how to automate the user input
this without some "expect" madness (any usable alternative to automate
the reply to a single prompt?).

So, since this is an operation that has to be done only on the setup
phase on few servers, for me is Ok to leave this step to manual
intervention, BUT still I want Puppet to notify (and keep on notyfing)
the user unless it finds oci8 ("unless  => "pecl info oci8").
I''ve tried with functions like warning or err but I haven''t
managed to
show their message on the puppet client and inside a resource (in this
case I was considering a sort of "fake exec", so that I could use the
mentioned uness parameter to check for the extension existence and
show the message only when necessary).

So, just to be clear.
I would like to know, in order of preference:
- How to automate in a sane way via pecl the oci8 installation
withouth using a package
- Or how to show a warning message explaining how to do that manually
when the module is not installed.

I have the feeling that the answer to the second question is somehow
trivial, but somehow not enought for me.
Oh, by the way, Puppetmaster is still 0.25

Any help appreciated. Final outcome will be made public on
example42.com as (almost) usual.

At the risk of raising your ire, are you aware that Oracle has already 
made php-oci8 packages:

Just wanted to make sure you were aware, as I''ve found many who are
not.

Cheers,
Avi

I have a similar problem. When trying to have puppet setup a hadoop
namenode it may need to format the hdfs if this is a first time
install. This requires giving the hadoop namenode -format command a
"Y" for each disk being formatted. Ideally in addition to feeding the
right prompt response we''d also be able to run external logic to
determine if it really is safe to do the format to protect against
accidental data loss. Is there something better than an expect script,
or worse just piping the yes command at it?

Hardly controlling my ire ( :-) ) I must confess that the server is
(sadly) an Ubuntu 10.04...
Thanks anyway
