I did. This gets me the error included below. Note how I am actually
passing post_start_commands as arguments to the action setting in my
jail.local file, just like it is being done for protocol and port.
Thus, I was assuming I was *not* mixing things up but rather did it
right. :)

[Yaroslav Halchenko]

it is hard to see whole picture since you are just sending changing
snippets of configuration - send the whole entirety...

I bet that the reason for current issue is that  
you defined actionstart in [Definition] config/action.d/iptables.conf
whenever you defined in post_start_commands in [Init] --- how can it see
its value in Definition?? define it in new section [DEFAULT] of the same
file then... and you might need to define it to smth nonempty - I am not
sure what freaks ConfigParser out exactly

once again - this is not a fail2ban issue but rather logic behind usage
of python interpolations in config files
