Dynamic reconfigurations of bird - how?

[Douglas Fischer]

I remember talking a little bit about something similar in the past here on
the list.

Something I had suggested, which I already use to a certain extent, is to
separate the settings of different snippets into different files, with
includes.

For example, everything that is common is in a main file.
Everything that is downstream prefix-list is each one in its file (Ex:
AS1234_prefix.conf)

>From a settings organization point of view, this helps a lot!
It also makes it easy to see in git which files have changed over time.

But that doesn't change the BIRD reload at all.
Unfortunately.
