Bird-1.6: failed configure check and exit status 0

[fatal]

Hello,

I'm using bird 1.6.3 on Debian Stretch and am trying to automate the
installation and configuration with ansible. Therefore the "configure
check" feature of bird comes in handy. Unfortunately the return code is
always "0" whether the config is OK or KO.

$ sudo /usr/sbin/birdc configure check

BIRD 1.6.3 ready.
Reading configuration from /etc/bird/bird.conf
Configuration OK

$ echo $?
0

After invalidating the config file:

$ sudo /usr/sbin/birdc configure check

BIRD 1.6.3 ready.
Reading configuration from /etc/bird/bird.conf
/etc/bird/bird.conf, line 7: syntax error

$ echo $?
0

I can build my playbook around this with grepping for "Configuration OK"
in the output[1], but it would be nice to habe bird return a non zero
value if the config check fails.

Thanks a lot

regards

Sam
