That's kinda what I'm looking for, but it can't be interactive as
there's no way to send input during the installation.
It should pass the DROP statements to the interpreter and the
interpreter takes the input and runs os.rmdir() or something similar.
This way the backend does all the work and the frontend
is easily configured for any user to add directories.
* %post --interpreter #!/usr/bin/myinterpreter
** DROP /tmp/directory
** DROP /tmp/directory2*

I'm not sure I understand what you're doing, but maybe you'll find the
following somewhat useful:
>>> import code
>>> class MyInterpreter(code.InteractiveConsole):
... def raw_input(self, prompt=None):
... # override input function
... while 1:
... text = raw_input(prompt)
... if text.startswith("DROP"):
... # deal with custom command
... print "CUSTOM DROP COMMAND", text
... return text
>>> i = MyInterpreter()
Python 2.5.2 [...]
Type "help", "copyright", "credits" or "license" for more information.
>>> print "hello"
>>> DROP something
CUSTOM DROP COMMAND DROP something
>>> x = 10
>>> y = 20
>>> x + y
>>> DROP something else
CUSTOM DROP COMMAND DROP something else
