Stop leaking host GIDs into VM via rsync -a

Replace 'rsync -az' with 'rsync -rlptDz' (archive minus owner/group
preservation). Running as a non-root user on the VM, rsync can't
preserve UID anyway, but it was successfully preserving GID whenever
the numeric GID happened to exist on the target. That caused synced
dirs (~/.aws, ~/.config/opencode, ~/.config/nvim, ~/.agents/skills,
~/.ssh) to end up with group 1001 on the VM, which was confusing
and, for group-writable mode, potentially insecure.

With -o and -g dropped, received files get the receiving user's
UID:GID (devbox:devbox), which is what you want.

 - **Project files** (`/workspace`) are always safe — they're your host filesystem.
 - **opencode config** is auto-generated from `OPENCODE_PROVIDER` env var on each start if no existing config is found. To persist config changes, mount the config directory from the host (see Custom opencode Config below).
-- **opencode data** (session history, memory) is lost with `--rm` unless you add a named volume.

+# Deploy — Host VM setup
+
+Scripts for setting up a fresh Linux VM to host opencode-devbox.
+
+## Files
+
+- **`cloud-init.yml`** — cloud-init user-data template for automated VM provisioning on OpenStack, Proxmox, or any cloud with cloud-init support
+- **`setup-host.sh`** — interactive post-install script for VMs that weren't provisioned with cloud-init
+- **`setup-openstack-secgroup.sh`** — creates an OpenStack security group with the right rules (SSH, mosh, ICMP)
+- **`sync-to-vm.sh`** — syncs local config directories (`~/.aws`, `~/.config/opencode`, etc.) to a remote VM based on which bind mounts are active in its `docker-compose.yml`
+
+## Supported distributions
+
+- **Debian 13 (Trixie)** — recommended (matches opencode-devbox base image)
+- **Ubuntu 24.04 LTS** — also works
+
+Other distributions will need manual adaptation.
+
+## Quick start
+
+### Option 1: Cloud-init (automated)
+
+Customize `cloud-init.yml` — replace the SSH public key and optionally the hostname/timezone. Then use it during VM creation:
+
+- **Proxmox**: attach as cloud-init user-data
+- **OpenStack**: pass via `--user-data` flag (see full example below)
+- **AWS/DigitalOcean/etc**: paste into the "user data" field
+
+#### Full OpenStack example
+
+Cloud-init only handles guest configuration — flavor, image, network, and security group must be specified explicitly at creation time.
+
+> **Note:** Do not use `--key-name` — the SSH key is configured in `cloud-init.yml` under `ssh_authorized_keys` for the `devbox` user. The `--key-name` flag injects into the image's default user (e.g. `debian`), not the `devbox` user created by cloud-init.
+
+```bash
+# List available flavors to choose appropriate sizing
+openstack flavor list
+
+# Create the security group first (one-time, see below)
+./setup-openstack-secgroup.sh
+
+# Basic — boot from default storage
+openstack server create \
+  --flavor c4m8 \
+  --image Debian-13-Trixie \
+  --network my-network \
+  --security-group opencode-devbox \
+  --user-data cloud-init.yml \
+  devbox-vm
+```
+
+If your cloud offers NVMe-backed (performance) volumes, boot from one for faster Docker and build I/O:
+
+```bash
+# Performance — boot from NVMe volume (40GB, preserved on instance deletion)
+openstack server create \
+  --flavor c4m8 \
+  --network my-network \
+  --security-group opencode-devbox \
+  --user-data cloud-init.yml \
+  --block-device source_type=image,uuid=$(openstack image show Debian-13-Trixie -f value -c id),destination_type=volume,volume_size=40,delete_on_termination=false,boot_index=0,volume_type=performance \
+  devbox-vm
+```
+
+> **Note:** The inline `volume_type` parameter requires API microversion 2.67+. If the server goes to ERROR state, check your volume quota (`openstack quota show`) and try creating the volume separately:
+> ```bash
+> openstack volume create --image Debian-13-Trixie --size 40 --type performance --bootable devbox-boot-volume
+> openstack server create --flavor c4m8 --volume devbox-boot-volume --network my-network --security-group opencode-devbox --user-data cloud-init.yml devbox-vm
+> ```
+
+#### Floating IP
+
+OpenStack doesn't support assigning a floating IP at instance creation time — it's a separate step after the VM is active:
+
+```bash
+# Allocate a new floating IP from the external network
+openstack floating ip create <external-network>
+
+# Assign it to the VM
+openstack server add floating ip devbox-vm <floating-ip>
+```
+
+To find your external network name: `openstack network list --external`. If you already have an unassigned floating IP, skip the create step.
+
+The VM boots with Docker installed, firewall configured (or skipped on OpenStack), and your SSH key authorized. Log in as the `devbox` user.
+
+### Console password (optional)
+
+The cloud-init template uses SSH key authentication only — no password is set by default. This is sufficient for normal use since the `devbox` user has passwordless `sudo`.
+
+A password is only needed for:
+
+- **Emergency console access** — logging in via OpenStack Horizon console (noVNC) or Proxmox VNC when SSH is unreachable
+- **`su - devbox`** — switching to the devbox user from another account
+
+To enable console access, uncomment the `chpasswd` block in `cloud-init.yml` before deploying:
+
+```yaml
+chpasswd:
+  expire: false
+  users:
+    - name: devbox
+      password: your-password-here
+      type: text
+```
+
+For an already-running VM, set a password via SSH:
+
+```bash
+sudo passwd devbox
+```
+
+### Option 2: Post-install script (manual)
+
+On a fresh Debian/Ubuntu VM:
+
+```bash
+curl -fsSL https://gitea.jordbo.se/joakimp/opencode-devbox/raw/branch/main/deploy/setup-host.sh | bash
+```
+
+Or clone and run:
+
+```bash
+git clone https://gitea.jordbo.se/joakimp/opencode-devbox
+cd opencode-devbox/deploy
+./setup-host.sh
+```

+- Docker Engine (from Docker's official apt repo, not distro's `docker.io`)
+- Docker Compose plugin (v2)
+- `tmux`, `mosh`, `git`
+- `ufw` firewall with SSH (22) and mosh (UDP 60000-61000) allowed — **skipped on OpenStack** (detected automatically; use security groups instead)
+- IPv4 DNS preference (works around Docker Hub IPv6 connectivity issues)
+
+## OpenStack security groups
+
+On OpenStack, firewalling is handled by security groups rather than ufw. The `setup-host.sh` script detects OpenStack automatically and skips ufw configuration.
+
+To create the required security group:
+
+```bash
+./setup-openstack-secgroup.sh
+```
+
+This creates a security group named `opencode-devbox` with rules for SSH (TCP 22), mosh (UDP 60000-61000), and ICMP. Apply it to your instance:
+
+```bash
+# New instance
+openstack server create --security-group opencode-devbox ...
+
+# Existing instance
+openstack server add security group <instance-name> opencode-devbox
+```
+
+## VM sizing recommendations
+
+| Use case | vCPU | RAM | Disk |
+|---|---|---|---|
+| Minimum | 2 | 4 GB | 20 GB |
+| Recommended | 4 | 8 GB | 40 GB |
+| Heavy use (Rust/Python builds, multi-project) | 8 | 16 GB | 80 GB |
+
+## After VM setup
+
+If you uncomment any bind mounts in `docker-compose.yml` (e.g. `~/.aws`, `~/.config/opencode`), create the directories first — Docker creates missing bind mount paths as root-owned, which causes permission issues:
+
+```bash
+# Only create directories for mounts you uncomment
+mkdir -p ~/.aws                  # AWS Bedrock SSO
+mkdir -p ~/.config/opencode      # persistent opencode config
+mkdir -p ~/.config/nvim          # custom neovim config
+mkdir -p ~/.agents/skills        # opencode agent skills
+```
+
+Named volumes (`devbox-data`, `devbox-uv`, etc.) are managed by Docker and need no pre-creation.
+
+```bash
+mkdir -p ~/opencode-devbox && cd ~/opencode-devbox
+curl -sL https://gitea.jordbo.se/joakimp/opencode-devbox/raw/branch/main/docker-compose.yml -o docker-compose.yml
+curl -sL https://gitea.jordbo.se/joakimp/opencode-devbox/raw/branch/main/.env.example -o .env
+vim .env                                           # configure provider and keys
+vim docker-compose.yml                             # uncomment optional volume mounts
+docker compose up -d
+docker compose exec -u developer devbox opencode
+```
+
+> **AWS Bedrock users:** Uncomment the `~/.aws` volume mount in `docker-compose.yml` before starting. You'll also need to copy your `~/.aws/config` from a machine where SSO is already configured, then authenticate inside the container with `aws sso login`.
+
+### Syncing local config to the VM
+
+After editing `docker-compose.yml` on the VM to uncomment the bind mounts you need, run `sync-to-vm.sh` from your local machine to copy the corresponding directories:
+
+```bash
+./deploy/sync-to-vm.sh devbox-affection
+```
+
+The script reads `docker-compose.yml` on the remote VM, detects which bind mounts are active, and syncs only those directories from your local machine. It also creates the remote directories if they don't exist.
