FreeNAS as a VM question(s)

[Octopuss]

I'm redoing my installation and since there are conflicting guides/information on the interwebs, I'd like to hear your opinions.

Should the disk the system itself will reside on be thin or thick provisioned? What's a reasonable capacity with a bit of a headroom? I don't plan to run many or any at all jails. It's just a file server. I feel like the original 32GB I went with was a colossal waste of space (thick provisioned even, that would suck to backup).

And then, is there any point in giving FreeNAS its own connection? I'm upgrading the house switch to 10GBit, so I guess a single 10GBit connection for the entire server should be perfectly fine and there's no need to separate it from other LAN connections.

I'm using VMware and have FreeNAS running as VM.
It has a 8GB thick provisioned disk and 1.6GB is used for now (and I'm running FreeNAS 9.10.x).
I'm don't do any backup of the boot device. I just do a backup of the config and I don't need more to restore it quite quickly.

And I'd guess that the system's size on the boot device is independent of the running jails jails, i.e. the system won't eat up (that significantly) more space if more jails are running. Actually I never paid attention to that I have to admit. Maybe someone can confirm that?
