January 2025: Delivered a critical subnet fix and virtualization integration in freifunk-berlin/bbb-configs. Corrected l105 subnet mask from /28 to /24 and added qemu-guest-agent (qemu-ga) to the package lists for ak36 and l105 hosts. Implemented in commit 466ae5275a62350f1f5d1aa1a500e1176ab62b58. This reduces misconfigurations and improves VM orchestration.
