Does kickstart run the packages' postinstall scripts?

[Dan Poirier <poirier fastmail fm>]

Does kickstart run the postinstall scripts for the packages it
installs from %packages?  It is looking as if it doesn't, and I need
the postinstall scripts to run for my packages or they aren't properly
installed.

Is there an option to have it do that, or some workaround?  I'd rather
use a custom comps file and %packages to install everything, than to
have to run rpm myself from %post or something.

Thanks!
