[Resolvconf-devel] Bug#676804: resolvconf fails when network-manager brings up a statically-configured interface

[Johannes Kloos]

Package: resolvconf
Version: 1.66
Severity: important

Hi,

after the latest update, resolvconf and network-manager will not play
well with each other anymore. With all scripts as is, the post-ifup
script of resolvconf is called by network-manager, but fails to add a
resolv.conf entry for the appropriate interface.
Further digging reveals that NetworkManager sends ADDRFAM to
NetworkManager (cf. my modifications in 000resolvconf below) instead of
inet or inet6.
Since this behaviour first occured due to a resolvconf update, I'm
reporting it here; feel free to re-assign to network-manager if more
appropriate.

Best regards,
Johannes
