You can make a package though, where everything lives under /config, preferably
/config/opt - right?
Like I said: Not a good idea to have your routing-engine and -config wiped
after a software update.
You can, however, put a "normal" BIRD install package into
/config/data/firstboot/install-packages and have a script in
/config/scripts/firstboot.d which may restore the config file (or a symlink to
/config/bird.conf, which also survives the big culling). In that case the
package gets re-installed early during the first boot after a FW update (and
the script called).
If the BIRD distribution depends on other packages, those also need to go into
/config/data/firstboot/install-packages.
And of course you need to have scripts updating the packages in
/config/data/firstboot/install-packages, when you update them ...
