[ixpmanager] BIRD2 configuration question

[Tom Duff]

Hi everyone,

We're trying to transition from Birdv1 to v2 at our IX, and I was
looking through the ixpmanager mailing list archives to see if anyone
had any info about running two instances of BIRD v2 on the same box. I
saw this thread in which it was explained the decision behind not
unifying the config:

 https://www.inex.ie/pipermail/ixpmanager/2019-August/002328.html

...which makes sense to me, but I've gone through all the bird docs,
and I cannot for the life of me figure out how to run an apt-installed
version of BIRD 2.0.7 as two separate daemons. I'm now thinking
there's no way to use the packaged version of bird, and compiling two
separate instances of BIRD v2 and running one with the IPv4-specific
config and one with the IPv6-specific config is what people are doing?
 Or is there some kind of compile-time flag that spits out the two
separate binaries (bird and bird6) like bird v1 used to have? I could
use a nudge in the right direction

Thanks,

--Tom
