[Bug 876829] Re: Oneiric's ifupdown breaks ip aliases

[Gareth Bult]

Ok, I tried this patch, improved things slightly but this package still seems heavily broken in terms of impact in the user. Anyone running aliases (I have maybe 50 servers that use aliases) who tries to upgrade to 11.10 is likely to end up with a broken server.
- is there some way we can generate a working fix for this, we're three weeks on from the report date it's an issue that can leave remote servers unreachable.

Specifically, anyone using KVM is likely to have a "br<n>" device.

It's quite common to use aliases for testing, for example "br0:test",
and even with the above patch, "ifdown br0:test" will actually take down
"br0" leaving the machine unreachable.

After applying the above patch, /etc/init.d/networking restart still
does not bring up all aliases, however a subsequent "ifup <alias>" does
.. don't know why this is the case, but it looks like more is required
to make this work.
