Good morning

Time goes quick, and we are working on getting the the Fedora audio spin (now called Fedora jam) ready for wrangler/review. There are a few questions we have we hope you can help us find the answer to. If you find it too much to write, i can come by the IRC channel for a meeting with you and discuss there instead.
Anyway, here are the questions i have gathered up:

1 kernel parameters ( threadirqs in our case) how (can?) we add them to the Live system and on install?

2 is it possible to modify sysconfig files in / owned by other packages? - ie. changing the default values in /etc/pulse/daemon.conf .

3 is it possible to change/set config items in /home/<installed_user> ? (e.g. /home/<user/.pulse - which would be a solution if (2) is not possible)

4 adding items to /etc/xdg/autostart (to autostart apps by default for all users).

5 (related to #4) can we drop files into ~/.config/autostart as part of the install process for the default user?

6 and which if any of these things can we do for the Live user?

7 How much can be changed in the kickstart file after submission?
