@nbd today's netifd push breaks existing setup using the alias syntax, i.e. the following breaks with the commented out line:
config bridge-vlan
option device 'itch0'
option vlan '10'
list ports 'lan4'
list ports 'lan3'
list ports 'lan2'
list ports 'lan1'
option alias 'lan'
config interface 'lan'
option device 'itch0.10'
# option device 'itch0.lan'
option proto 'static'
option ipaddr '192.168.10.1'
option netmask '255.255.255.0'
option ip6assign '60'
with no static router IP / bridge-vlan setup.
