 - `host` - Hostname (e.g., `ns1`, `ns2`, `monitoring01`, `ha1`). Use this label, not `hostname`.
 - `systemd_unit` - Systemd unit name (e.g., `nsd.service`, `prometheus.service`, `nixos-upgrade.service`)
-- `job` - Either `systemd-journal` (most logs) or `varlog` (file-based logs like caddy access logs)
+- `job` - Either `systemd-journal` (most logs), `varlog` (file-based logs), or `bootstrap` (VM bootstrap logs)
 - `filename` - For `varlog` job, the log file path (e.g., `/var/log/caddy/nix-cache.log`)
 
 Journal log entries are JSON-formatted with the actual log message in the `MESSAGE` field. Other useful fields include `PRIORITY` and `SYSLOG_IDENTIFIER`.
 
+**Bootstrap Logs:**
+
+VMs provisioned from template2 send bootstrap progress directly to Loki via curl (before promtail is available). These logs use `job="bootstrap"` with additional labels:
+
+- `host` - Target hostname
+- `branch` - Git branch being deployed
+- `stage` - Bootstrap stage: `starting`, `network_ok`, `vault_ok`/`vault_skip`/`vault_warn`, `building`, `success`, `failed`
+
+Query bootstrap status:
+```
+{job="bootstrap"}                              # All bootstrap logs
+{job="bootstrap", host="testvm01"}             # Specific host
+{job="bootstrap", stage="failed"}              # All failures
+{job="bootstrap", stage=~"building|success"}   # Track build progress
+```
+
 **Example LogQL queries:**
 ```
