## Resource

Learn how to build custom, modern live rescue environments to recover data from failing systems. The episode explores tools like Aegis Boot and NixOS to create portable, secure, and automated troubleshooting toolkits.

## Highlights
- Main idea: Creating a custom live rescue environment is more efficient than relying on generic, outdated bootable media
- Practical takeaway: Use Aegis Boot to maintain a UEFI Secure Boot chain of trust while booting various Linux ISOs from a single USB
- Practical takeaway: Leverage NixOS modules to build highly customized, reproducible, and lightweight rescue environments with minimal code
- Failure mode: Avoid high-bandwidth data transfers during recovery to prevent overheating USB drives during sensitive data rescue operations
- Tool recommendation: Use Heron's Boot CD for specialized Windows PE-based rescue tasks when dealing with Windows-specific environments

## Topics
