[Pkg-utopia-maintainers] Bug#682497: init.d: LSB headers: please Provides: $network

[Michael Biebl]

Hi,

network-manager does not block during boot until a network connection is
established contrary to ifupdown.

Letting the network-manager sysv init script provide $network would be
wrong because of that, because network-manager being started doesn't
mean a network connection is available.

network-manager ships a tool called nm-online, which blocks until a
network connection has been established (or an optional timeout is reached).

This tool is used in
 /lib/systemd/system/NetworkManager-wait-online.service:

[Unit]
Description=Network Manager Wait Online
Requisite=NetworkManager.service
After=NetworkManager.service
Wants=network.target
Before=network.target

[Service]
Type=oneshot
ExecStart=/usr/bin/nm-online -q --timeout=30

[Install]
WantedBy=network.target


This systemd service is not activated by default, as it is only a
hack/workaround for broken software which can't handle dynamically
changing networks.

A similar service could be written for sysv. Such a service could have a
provides: $network.

Cheers,
Michael
