Takze konfigurace prevzata z Debian 9 na Debian 10 vygeneruje jina zarizeni.

Dal me prekvapilo, ze polozka u br0:

bridge_vlan_aware yes

muze byt aktivni nebo za # a zafunguje stejne, takze fakticky mam funkcni konfiguraci pro Debian 10, ale s pochopenim jsem zase na zacatku.

Vypis:

ip a sh

pro ilustraci vygenerovanych devices nejsem schopen sem dat, protoze vetsitka a mensitka to tady bere jako html znacky.
