I'm not a very large user case: i've many PVE system, but they are 4.4
and not ''firewalled'', this is a 5.2 and a case ''per se''...

In a ''falied'' boot i can se the logs for interfaces 'lo' and '--all'
(why '--all'?). Logs report, for every interface:
	/bin/ip link set dev <iface> up
and then the run of the 'run-parts':
	run-parts: executing /etc/network/if-up.d/0sysctl
and the the single runs of the scripts:
	run-parts: executing /etc/network/if-up.d/bridgevlan

In a good boot, i can se the logs for interfaces 'lo', 'vmbr0', 'vmbr1'
and '--all''. Same logs.

My script are parametrizied, and get runned only on particular

I was short on time, and so i was forced to put that server
in production, in a non too easy reachable place.

So, now i cannot play with networking. ;-)
