Use with Proxmox Cloud-Init:

• Build template
  • Do stuff..
  • Use as base image:
    • https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img
    • https://cloud-images.ubuntu.com/noble/current/noble-server-cloudimg-amd64.img
    • Resize image:
      • qemu-img resize jammy-server-cloudimg-amd64.img 8G
      • qemu-img resize noble-server-cloudimg-amd64.img 8G
• Execute somewhere ./proxmox/new_ci-config.sh
• Store 'ci-config-userdata.yaml' in Proxmox Snippets
• Store 'ci-config-vendor.yaml' in Proxmox Snippets
• Update your template VM:
  • qm set <vmid> --cicustom "user=local:snippets/ci-config-userdata.yaml"
  • qm set <vmid> --cicustom "vendor=local:snippets/ci-config-vendor.yaml"

Recommended partition layout

Mount Point	Size	Filesystem (Recommended)	Remarks
/	32 GB	ext4	Root filesystem. Sufficient for base OS, packages, updates.
/home	8 GB	ext4	User data isolation.
/var	8 GB	ext4	Variable state data. Logs excluded. Monitor space usage.
/var/log	8 GB	ext4	Log isolation to prevent root exhaustion.
/var/log/audit	4 GB	ext4	Dedicated audit trail partition (auditd). Prevents log flooding impact.
/var/tmp	1 GB	ext4	Persistent temp storage across reboots.
/tmp	1 GB	ext4 or tmpfs	Ephemeral temp storage. Prefer tmpfs if RAM allows.
/opt/data	x GB + remainder	ext4 or XFS	Primary persistent data storage.
