More playing with OpenVZ

Ok I'm revisiting my OpenVZ templates and been thinking about packaging as a distributable item (not sure if there's a lot of demand but still ...)

Now, I have a couple of questions:

1. Have you any suggestions on why the confconsole doesn't run at boot as it should? Any ideas on where to start with that one?
2. As I mentioned back in my original OpenVZ topic I can get the confconsole to run, but unless I set the network to be bridged (and use DHCP initially) it configures the wrong interface. Is there a way to adjust which interface the confconsole configures?
3. Is there a way I can invoke the install config console on an already installed machine (ie the password requests etc, obviously not the partitioning stuff) or is that going to be too painful? Would devising a separate 'first run' config script be a better option?
4. Following on from that, what would be the best way to get a script to run once only (on first boot)? I gather that update-rc.d is the go but would you just set it to run everytime but have the script itself remove its startup entry or is there another way? I've heard that cron can run scripts "on boot/reboot" and "on next boot/reboot", also in my googling I have come across mention of a "skeleton file" which I have no idea about.

If I can get these sorted out I'll happily upload my templates somewhere so others can play with them if they desire. Or perhaps I'd be better off providing my OpenVZ template creation script (which I've already been using for my own purposes, but it would need a lot of polish to share) and let users work that out themselves?
