[Pkg-utopia-maintainers] Bug#1108086: network-manager: please make bin:network-manager Conflicts bin:dhcpcd

[Martin-Éric Racine]

Package: network-manager
Severity: normal
X-Debbugs-Cc: martin-eric.racine at iki.fi

See corresponding dhcpcd bug #1107683.

Out of the box, network-manager and a daemonized dhcpcd (launched by the init.d script or systemd units provided by bin:dhcpcp) takes control of all network interfaces.

Installing both packages on the same host results in both daemons constantly trying to hijack control over the interfaces from each other. This is obviously undesirable. The only fix I can think of is to make these 2 packages mutually Conflicts.

I cannot think of any other case for conflicting with other packages, since ifupdown does nothing until /etc/network/interfaces is populated (and network-manager knows how to skip any interface defined there), and networkd requires manually creating units for the interfaces then unmasking the daemon to have it lauch, and dhcpcd-base only ships binaries needed by ifupdown or network-manager's dhcpcd backend but doesn't launch anything out of the box.

If you can think of a better way to handle this, I'm listening.
