Commissioning failed during 1st pxe install 24.04

This is working in Jammy 22.04

initramfs-tools replace dhclient with dhcpcd. We should probably do the same: https://git.launchpad.net/~ubuntu-core-dev/ubuntu/+source/initramfs-tools/commit/?id=3358bc078714a2574b315e6a037bee0658cb36d3

Using Noble for commissioning won't work until the scripts are updated to use an alternative dhcp package. This affects all MAAS versions, so we'll need to update the scripts on all supported releases. In the meantime, we can promote the Noble image to the stable channel, but it needs to be clear to the operators that changing the default commissioning image may result in errors.

The workaround is to keep using the default Ubuntu LTS version until the scripts are updated to use a different dhcp client, or to add a new commissioning script that installs isc-dhcp-client (from noble/universe) before the failing commissioning script is run.

FWIW, I ran into this on maastiff (a recent rebuild/replacement for the failed weavile), but not on a MAAS server on my home network. Both are running MAAS 3.4.2, but they may have different ephemeral images installed.

Can Noble squashgs contain both dhcpcd and dhclient at the same time or are they conflicting packages ?
Alternatively, can dhcpcd contain a wrapper script that provides dhclient compatible cli experience ?

For #3,
- change Ubuntu 22.04 LTS for "Default Ubuntu release used for commissioning"
- you can deploy 24.04 after above passed

confirmed hitting this issue with noble during commissioning

I've tried this fix, seems to work:

root@maas-m:~# su -l postgres
postgres@maas-m:~$ psql maasdb

maasdb=# UPDATE maasserver_script SET packages = '{"apt": ["isc-dhcp-client"]}' WHERE name = '20-maas-02-dhcp-unconfigured-ifaces';

@tryauuum It works.
Thank you so much.

Im running MAAS: 3.4.6 installed via SNAP and I had this error when installing 24.04 release on servers
As a workaround I installed this script: script "10-maas-extra-packages" with the contents:

```
#!/bin/bash

apt update
apt -y install isc-dhcp-client

This is marked as "fix released" for MAAS 3.4 as of milestone 3.4.6, but I'm continuing to experience this issue on MAAS 3.4.7:
