[Bug 1989618] [NEW] [Feature Request] Include support for LACP bonds in initramfs

[Launchpad Bug Tracker]

Feature Request:

When installing a system over the network using live installer
(subiquity), you can use the kernel cmdline option ip= [1] to provide
the network configuration.

In certain situations, it would be ideal to be able to configure a lacp
bond during this process. Sometimes the network ports on the switch are
configured with lacp bond (802.3ad) and the switch won't let an
interface be brought up unless it sends lacpdus.

I've discussed this through a subiquity bug [2] and it was mentioned
that there doesn't seem to be any support in our initramfs for LACP
bonds [3]. It was requested for a new bug to be filed at the initramfs-
tools project for such functionality to get included.

I don't have any use case at the moment, but I've received this request
in the past when the customer was still using debian installer. For
debian-installer this was once discussed via a debian bug [4] and a
patch was proposed [5], but this was never accepted / merged.

Considering that Tte new installer is an _entirely_ different codebase
than d-i, the lacp support would have to come from the initramfs.
