remove an installed rpm during rpm -i

[Michael Barto]

If you can write a shell script to do this validation and/or the 
removal, then you can either embed it in the spec file or call a script 
remotely from inside the spec file. I posted a page the shows how to 
embed some shell commands and where they really are in the structure of 
the rpm. Say putting it in the %install section is my suggestion. Hope 
it helps as I did with adding the cron entries which was a simple copy 
(cp). I have seen some spec examples that actually call shell programs. 
My personal opinion is you should copy the external shell script to the 
working directory (the tar-gz file with the spec file as in the example) 
and run it from there, and then let the rpm program delete it.

This is an example I have from a spec file:

%install
sh ./installer.sh
