In frr repository there are tools/frr-reload.py script, which can 'reload' current configuration of frr daemons without restarting them (works only in integrated-config mode).
IMO frr pretty much useless without that tool as of now (YANG support and rollbacks is not ready). Can we get this script into main port? Or maybe into it's own port? For example it's distributed as frr-pythontools package for Linux.
And if we can there are couple of problems, that must be solved:
* where to put it? I'm not good in BSD hier, but maybe /usr/local/lib/frr will do (Linux use /usr/lib/frr/)
* how to execute it? FRR repo contains /tools/frr-reload shell script which call that python script in turn, but it is not included into frr-pythontools
* sed binaries hard-links. /usr/bin/python3 and /usr/bin/vtysh is not suitable for BSD
I tested script on FreeBSD 12.0-RELEASE with python 3.7 and looks like it works (both --test and --reload).
Adding this script will add python as running dependency to FRR.
So I like the idea of frr-pythontools port.
