Re: Bug#378714: vlan: installing package breaks proxy-arp config [sarge]
This is #330673.
From the 1.9-1 changelog:
* Fix /etc/network/if-up.d/ip to not set rp_filter to 1 when it isn't
configured. (Closes: #330673) [debian/ip-if-up]
I'm willing to prepare a SPU upload if the release team desires so.
I agree that it's an important bug when installing a package breaks
your network, I'm not sure whether it's suitable for stable though; it
is still unlikely that someone fiddles with VLANs without local access.
