Package: ifupdown
Version: 0.6.4-3planNET5
Severity: wishlist

It is a frequent case when taking down an interfaces affects another.
This applies, for example, to secondary IPs that go down with their
primary, or interfaces that host tunnels, taking down the tunnel
endpoint interfaces as well. There are also some dependencies when one
is using advanced routing options like source policy routing that is
initialized when the interface that hosts the possible source IP range
comes up.

Please consider adding a "depends" clause to the iface blocks that
causes ifupdown -a to build an initialization order that does honor
the dependencies, and that is used to refuse taking down interfaces
that other interfaces depend on and to refuse taking up interfaces
that need other interfaces being up to properly function.

I realize this might be a quite deep modification or ifupdown that
certainly wouldn't go into woody.

Greetings
Marc
