Replacing Postinst Scripts

[robert_joslyn at selinc.com]

Is there a good way to handle debian postinst scripts in Snappy? I have 
some debs that create users and setup configuration files during the 
postinst stage, and I would like to include these debs in a larger snap. 
How do I handle user creation and placing configuration files into 
$SNAP_APP_DATA_PATH? Is my application expected to do this on first run? 
Can I specify user creation and the user a service will run as in the 
package.yaml (or snapcraft.yaml)?

Thanks,
