Root cause: /etc/resolv.conf was a broken symlink to systemd-resolved's
stub resolver, which doesn't exist after disabling the service.
Fixed by creating proper /etc/resolv.conf pointing to dnsmasq on 10.42.1.1
and upstream resolvers (1.1.1.1, 8.8.8.8).
This fix allows apt-get to work again and enables podman installation.
**Result: ✅ podman installed, homeassistant container starting**

Added HOMEASSISTANT.md with migration steps and configuration details.
Home Assistant config copied to R5C at /srv/homeassistant.
**BLOCKED**: podman installation fails on R5C due to extreme network latency
(1000+ ms Starlink connection) and DNS resolution failures. Package downloads
fail consistently.
Migration can proceed once R5C network is stable enough for apt-get to complete.
