[pve-devel] seem than ifupdown2 is installed by default on upgrade (a friend reported me an ipv6 slaac bug)

[DERUMIER, Alexandre]

Hi,

I have a friend who's reported my than ifupdown2 had been installed by
default on pve 8.1 upgrade.

I think it's because pve-network have "Recommends: ifupdown2".


This proxmox server was installed with debian iso, with default ipv6 on
interface (auto eth0 inet6 ..).

Seem that it have impacted the slaac config.   (I had double check some
months ago ipv6 with ifupdown2, all was ok,  but maybe default
accept_ra is different if ifupdown2, not 100% sure ye)
