thank you for expanding on my gist!
just went to use my gist after a while and discovered you had expanded it!
would be amazing if you can expand it more and let users config everything right at the top of the script
like timezone, what network to attach, what nodeid to use rather than 9000
maybe even what ubuntu version too!

edit: you also forgot to add in the --scsi1 nas:cloudinit so it isnt adding in the cloudinit drive
edit2: you also forgot to add in the --efidisk0 so the is no UEFI bios to save secure keys etc into

Good suggestions and catches. I'll update it in a bit. I may have already done some of this in my scripts repo but I can't remember off the top

Yea here we go

Oh wow legend!
A few thing I've spotted, so I'll fork ur repo n make my own changes.
for example the user create and and update packages, don't need to be done in the image itself,
as u can specify these in the proxmox ui per vm and it gets done when u first start ur vm.
This lets u use the template as a template for customers :)

Also timezone is hard-encoded ans the cloud init for proxmox won't run because it needs to be attached to the scsi and not the ide (ubuntu thing if ur drives are attached as scsi instead of ide)
