# P0-007: Install Script Template Uses Wrong Path Variables

**Priority:** P0 (Critical)
**Date Identified:** 2025-12-17
**Status:** ✅ FIXED
**Date Fixed:** 2025-12-17
**Fixed By:** Casey & Claude

## Problem Description

The Linux install script template uses incorrect template variable names for the new nested directory structure, causing permission commands to fail on fresh installations.

**Error Message:**
```
chown: cannot access '/etc/redflag/config.json': No such file or directory
```

**Root Cause:**
- Template defines `AgentConfigDir: "/etc/redflag/agent"` (new nested path)
- But uses `{{.ConfigDir}}` (old flat path) in permission commands
- Config is created at `/etc/redflag/agent/config.json` but script tries to chown `/etc/redflag/config.json`

## Files Modified

- `aggregator-server/internal/services/templates/install/scripts/linux.sh.tmpl`
  - Line 310: `{{.ConfigDir}}` → `{{.AgentConfigDir}}`
  - Line 311: `{{.ConfigDir}}` → `{{.AgentConfigDir}}`
  - Line 312: `{{.ConfigDir}}` → `{{.AgentConfigDir}}`
  - Line 315: `{{.LogDir}}` → `{{.AgentLogDir}}`

## Verification

After fix, fresh install should complete without "cannot access file" errors.

## Impact

- **Fixed:** Fresh installations will now complete successfully
- **Why P0:** Blocks ALL new agent installations
- **Status:** Resolved
