[Vivo Fibra] Usando RTF3507VW-N1 em modo bridge

Por que usar o RTF3507VW-N1 em modo bridge?

O roteador Askey RTF3507VW-N1 fornecido pela Vivo tem vários problemas:

Existe um cache interno de DNS (usando o dnsmasq?) bugado: ao fazer a mesma requisição DNS duas vezes seguidas, a primeira resposta vem correta, porém na seguinte temos:

These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

set -euxo pipefail is short for:

set -e
set -u

All packages, except for Tini have been added to termux-root. To install them, simply pkg install root-repo && pkg install docker. This will install the whole docker suite, left only Tini to be compiled manually.
