Ubuntu template configuration?

[Colin 't Hart]

Hi,

I'm wondering how you create the Ubuntu templates that you make available. We have a number of developers that are still using Virtual Box (yes, I know...) and installing a virtual machine with a minimal Ubuntu server installation results in many more packages than what's in the Ubuntu templates used to make containers on Proxmox. So I'd like to know how you create these templates -- is this documented anywhere?

Many thanks,

Colin

I'm going to hijack my own thread: Why does the DAB include its own Postfix main.cf rather than installing the default one included with the postfix package?
This supplied main.cf has a bug: Running some Python code to connect to the SMTP server on localhost, port 25 would connect over IPv6. But mynetworks in this main.cf doesn't include the IPv6 addresses, so Postfix refuses to send the emails saying, "relaying denied".
Can you fix this? The best way would be to let Postfix install the main.cf, but maybe you have a really good reason for supplying your own?
