How about using RPM's %triggerin scriptlet?


For example, you could create a dummy rpm package containing a 
%triggerin scriptlet to run your scripts in the event that package foo 
gets installed/updated.

Lets take vmware as an example (although it's probably not a very good 
example). I assume you need to run vmware-config.pl after each kernel 
update and you sometime forget to do that. You could build and install a 
dummy package that contains a %triggerin scriptlet that triggers on 
installation of the package kernel. In an ideal world the %triggerin 
scriptlet would simply run /usr/bin/vmware-config.pl, but as that script 
requires user interaction, you'd probably have to call it with the 
--default flag to provide the default answers to all questions. 
Alternatively, you might decide not to run the vmware-config.pl script 
automatically but rather send an email to root or something else to 
remind you to run it.

Is that the type of solution you're looking for?
