Add seamless migration path from legacy agents to unified agent:
- Add AgentType field to report payloads (unified vs legacy detection)
- Update server to detect legacy agents by type instead of version
- Add UI banner showing upgrade command when legacy agents are detected
- Add deprecation notice to install-host-agent.ps1
- Create install-docker-agent.sh stub that redirects to unified installer
Legacy agents (pulse-host-agent, pulse-docker-agent) now show a "Legacy"
badge in the UI with a one-click copy command to upgrade to the unified
agent.
Fixes#755. Adds interactive pauses and graphical popups (where available) to installer scripts when critical errors occur, ensuring troubleshooting guides are readable. Also clarifies 'build from source' instructions.
Snap-installed Docker does not automatically create a docker group,
causing permission denied errors when the pulse-docker service user
tries to access /var/run/docker.sock.
Changes:
- Auto-detect Snap Docker installations
- Create docker group if missing when Snap Docker is detected
- Restart Snap Docker after group creation to refresh socket ACLs
- Add socket access validation before starting the service
- Handle symlinked Docker sockets in systemd unit ReadWritePaths
- Document troubleshooting steps in DOCKER_MONITORING.md
Adds build support for 32-bit x86 (i386/i686) and ARMv6 (older Raspberry Pi models) architectures across all agents and install scripts.
Changes:
- Add linux-386 and linux-armv6 to build-release.sh builds array
- Update Dockerfile to build docker-agent, host-agent, and sensor-proxy for new architectures
- Update all install scripts to detect and handle i386/i686 and armv6l architectures
- Add architecture normalization in router download endpoints
- Update update manager architecture mapping
- Update validate-release.sh to expect 24 binaries (was 18)
This enables Pulse agents to run on older/legacy hardware including 32-bit x86 systems and Raspberry Pi Zero/Zero W devices.

This commit addresses the Alpine Linux installation issues reported where:
1. The OpenRC init system was not properly detected
2. Manual startup instructions were unclear and used placeholder values
3. The agent didn't validate configuration properly at startup
Changes:
Install Script (install-docker-agent.sh):
- Improved OpenRC detection to check for rc-service and rc-update commands
instead of looking for openrc-run binary in specific paths
- Added specific Alpine Linux detection via /etc/alpine-release and /etc/os-release
- Enhanced manual startup instructions to show actual values instead of placeholders
- Added clearer warnings and guidance when no init system is detected
- Included comprehensive startup command with all required parameters
Agent Startup Validation (pulse-docker-agent):
- Added validation to detect unexpected command-line arguments
- Added helpful note about double-dash flag requirements (--token vs -token)
- Improved error messages to include example usage patterns
- Added warning when defaulting to localhost without explicit URL configuration
- Provide both command-line and environment variable examples in error messages
These improvements ensure that:
- Alpine Linux installations will properly detect and configure OpenRC services
- Users who must start the agent manually get clear, copy-pasteable commands
- Configuration errors are caught early with actionable error messages
- Common mistakes (like missing --url) are clearly explained
