Remember authorization / disable password for some actions in PolicyKit

[LoonyPhoenix]

Hey, everybody, I need some help tweaking my security options. I tried man pages of PolicyKit and Google, but couldn't find definitive answers, so here I am

Can I make some actions available automatically, without the password, with PolicyKit? For example, I don't want to have to enter my password every time I mount a partition. I understand I can configure permanent mounts with fstab, but I'd like to try it this way first Also, I would like to give Software Center permission to install and uninstall software without password authorization. And some other things. I understand it's a security risk, but hey, I don't have any sensitive data, and I'm not paranoid (so sue me). It's my call, isn't it?

PolicyKit is supposed to be the new and flexible system for organizing permissions, so I want it to do what I want it to do. But I can't figure out how

PS: I'm using Karmic
