bird systemd startup init debian

[Rob Lister]

Yes - thanks for that hint :)

The error "bird: Unable to open configuration file /etc/bird/bird.conf" 
appears in red text while
the smaller more critical reason does not stand out so much.

BIRD_ARGS in /etc/init.d/bird seems not to work (something else is 
overriding it?)

Both bird and bird6 pick up from /etc/bird/envvars but we need to define 
separate configuration files for bird and bird6.

My eventual fix for this:-

cp /etc/bird/bird.conf /etc/bird/bird-vlanid1-ipv4.conf
cp /etc/bird/bird.conf /etc/bird/bird-vlanid1-ipv6.conf
rm /etc/bird/bird.conf

cp /etc/bird/envvars /etc/bird/envvars6

echo "BIRD_ARGS=\"-c /etc/bird/bird-vlanid1-ipv4.conf\"" >> envvars
echo "BIRD_ARGS=\"-c /etc/bird/bird-vlanid1-ipv6.conf\"" >> envvars6

systemctl edit bird :

# bird.service
[Service]
ExecStart=
ExecStart=/usr/sbin/bird -f -u $BIRD_RUN_USER -g $BIRD_RUN_GROUP 
$BIRD_ARGS
ExecStartPre=
ExecStartPre=/usr/sbin/bird -p -f -u $BIRD_RUN_USER -g $BIRD_RUN_GROUP 
$BIRD_ARGS

systemctl edit bird6 :
# bird6.service
[Service]
EnvironmentFile=
EnvironmentFile=/etc/bird/envvars6
ExecStart=
ExecStart=/usr/sbin/bird6 -f -u $BIRD_RUN_USER -g $BIRD_RUN_GROUP 
$BIRD_ARGS
ExecStartPre=
ExecStartPre=/usr/sbin/bird6 -p -f -u $BIRD_RUN_USER -g $BIRD_RUN_GROUP 
$BIRD_ARGS
