I need to specify during startup "-c /path/to/config/file" but

I do, it just gets ignored and still tries to use /etc/bird/bird.conf
I have tried:
- Editing /etc/init.d/bird and adding BIRD_ARGS="-c
/etc/bird/bird-vlanid1-ipv4.conf"
- Editing /etc/defaults/bird (deprecated??)
Editing arguments should be done in /etc/defaults/bird, not in
/etc/init.d.
Yes, I tried both and neither worked, though the file does not exist by
default
(this is where the options are changed on our existing route servers.)
- Editing /etc/bird/envvars
- Editing the systemctl with "systemctl edit bird.service" as
suggested
here:
https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1503154.html
- Restarting systemctl daemon-reload
This only re-reads the systemd configuration file. Try "service bird
restart" (because reload only causes bird to reread the bird config and
if you want new command line arguments, restart bird)
Yes, tried that but it won't start while it can't find
/etc/bird/bird.conf, and I can't seem to tell it to use an alternative
configuration file. I've tried all of:-
root@rs1f:/etc/bird# cat /etc/bird/envvars
BIRD_RUN_USER=bird
BIRD_RUN_GROUP=bird
BIRD_ARGS="-c /etc/bird/bird-vlanid1-ipv4.conf"
root@rs1f:/etc/bird# cat
/etc/systemd/system/bird.service.d/override.conf
# bird.service
[Service]
ExecStart=
ExecStart=/usr/sbin/bird -c /etc/bird/bird-vlanid1-ipv4.conf -f -u
$BIRD_RUN_USER -g $BIRD_RUN_GROUP $BIRD_ARGS -P /var/run/bird/bird.pid
root@rs1f:/etc/bird# grep BIRD_ARGS /etc/init.d/bird
BIRD_ARGS="-c /etc/bird/bird-vlanid1-ipv4.conf"
root@rs1f:/etc/default# cat /etc/default/bird
#
# This is a POSIX shell fragment
#
# Additional options that are passed to the Daemon.
BIRD_ARGS="-c /etc/bird/bird-vlanid1-ipv4.conf -s
/var/run/bird/bird-vlanid1-ipv4.ctl"
Also tried the old "DAEMON_ARGS" here but doesn't look like the script
uses it.
But whatever I try doesn't get passed to bird:-
root@rs1f:/etc/bird# service bird start
Job for bird.service failed because the control process exited with
error code.
See "systemctl status bird.service" and "journalctl -xe" for details.
root@rs1f:/etc/bird# systemctl status bird.service

Seems that /etc/bird/envvars should be being read:
/etc/init/bird.conf
root@rs1f:/etc/init# cat /lib/systemd/system/bird.service

After some further investigation, It would seem that something is
checking for /etc/bird/bird.conf during startup regardless,
and failing even if this file is not specified:
If we do:
root@rs1f:/etc/bird# ln -s bird-vlanid1-ipv4.conf bird.conf
root@rs1f:/etc/bird# service bird start
root@rs1f:/etc/bird# !ps
ps xau | grep bird
bird 313 0.0 0.0 15332 2088 ? Ss Mar05 0:00
/usr/sbin/bird6 -f -u bird -g bird
bird 1609 0.0 0.0 15272 2084 ? Ss 10:49 0:00
/usr/sbin/bird -f -u bird -g bird -c /etc/bird/bird-vlanid1-ipv4.conf
It appears that it took my config as specified from "/etc/bird/envvars"
but that it cannot cope with /etc/bird/bird.conf not existing.
(We tried also just a blank /etc/bird/bird.conf but it doesn't like that
- must be valid config file.)
